Celebrity Voice Actor: El Guapo, the announcer of Nexomania, is voiced by Arturo "El Rudo" Rivera, a famous lucha libre commentator.
Development Hell: The first concept for Heroes of the Storm was Blizzard Dota, shown in 2010, as a Mod for Starcraft II. It was shown again as Blizzard All-Stars in 2011, then there was little to no news about it (save for the reassuring news that it'd been scrapped and reworked twice) until November 2013. COMING SOONISH indeed.
Dummied Out: The Mega Enforcer didn't fit into how the new Hanamura Temple worked, so it got the axe instead.
Executive Meddling: Blizzard's decision to scale back support for the game is commonly seen as a result of Activision's efforts to cut costs throughout the company, something supported by Blizzard's layoffs around that time. Since it was the least popular of Blizzard's core active games, and the one with the least amount of revenue that could be made, it was easier to scale it back.
Fan Nickname: There's a few for the heroes and combinations of their abilities.
Abathur's Symbiote is commonly called a Hat. Abathur himself is sometimes shortened to "Abby" or sometimes ABBA. The rare Abathur who achieves a kill with his basic attack is referred to as a "Slapathur."
Azmodan's Q ability (Globe of Annihilation) gets called the "Azmodunk". Sometimes extends to Azmodan himself.
Right after official art for Whitemane was released, players called her "Thigh Inquisitor" because, uh... well.
Zagara and Zeratul are sometimes shortened to "Zag" and "Zera" respectively. Really, any Hero whose name can be chopped down for the sake of brevity in chat tends to have this happen (Kael'thas = Kael/KTnote The latter has largely fallen out of favor, now being used to address Kel'Thuzad., Azmodan = Azmo, Gazlowe = Gaz, Orphea = Orph, Leoric = Leo, Samuro = Sam, Illidan = Illi, Kerrigan = Kerri, Malfurion = Malf, Muradin = Mura, Nazeebo = Naz, Tassadar = Tass, Brightwing = BW, Deathwing = DW, Anub'arak = Anub, The Lost Vikings = TLV, Sylvanas = Sylv, Kharazim = Khara, Ragnaros = Rag, Imperius = Imp, Stukov = Stu, Malthael = Malth, Garrosh = Gary, Junkrat = JR/Rat, Alexstrasza = Alex, Artanis = Art/Arty, etc.)
Zeratul Void Prison + E.T.C. Mosh Pit w/Tour Bus = Prison Bus
Any sufficiently strong combination (usually of Heroic Abilities) generally is designated a Wombo Combo.
The boss camp on Sky Temple (any boss camp, really) is often known as the Throw Pit because of the number of games that get decided there when one team tries to take the boss, then the other team comes in, wipes them, and steals the boss.
The Punishers on Infernal Shrines have become known as John Cenas, thanks to a video that was shortly made after its spotlight was revealed. The casters at the Americas Cup on September 19-20, 2015 went along with the joke and started calling them John Cena a couple times. CarBot then made a parody based on this.
Dehaka's Q ability (latching onto and dragging people with his tongue) has given him the name "Zerg Yoshi".
Li-Ming is usually called with a shortened 'Ming'. Aside of that, calling her 'Azula' still works just like in her origin. Alternatively, people reversed her name into 'Ming-Li' or (especially among the Twitch crowd) "MingLee."
Chen's Storm, Earth, and Fire heroic is often referred to by commentators as "Panda Pals".
Gul'dan's Rain of Destruction is often referred to as "Rain of RNG" because of the random placement of the meteors.
For whatever reason, Diablo is usually referred to as "Dibbles"note This may be related to players mocking him as "Dibbles, Lord of Weakness" prior to his Balance Buff, and the name has stuck even after.
Lying Creator: After Blizzcon 2015, Blizzard seemed to emphasize that there wouldn't be a specialist for awhile...only to announce that Xul (Necromancer) would be a melee specialist. However, by the time Xul actually reached the Nexus (1 March 2016), nearly a year passed since the last specialist's arrival (Sylvanas, released on 24 March 2015).
In the Latin American version, all the characters from other Blizzard's games dubbed in Latin American Spanish had different voice actors, as the dub was made in Argentina, while previous games were dubbed in other Latin American countries like Colombia (World of Warcraft and StarCraft) or Mexico (Diablo III). Oddly enough, this was averted with both Tracer and Cain, whose voice actors are Mexicans.
When Fenix joined the roster in his first appearance since Brood War, he retained his Other Darrin voice actor, Marc Graue, that his robotic copy, Talandar, received in Legacy of the Void, making it a weird, semi-retroactive example of this. See What Could Have Been for details.
Even original characters aren't exempt from this. When Battlefield of Eternity was added to the game, Ilarian was clearly voiced by Jonathan Adams, sounding uncannily like his voice for Tyrael. Perhaps to stave off confusion between the two characters, Ilarian was given a new voice by the time Infernal Shrines was added.
Role Reprise: Damn near everyone is brought back by Blizzard to voice their characters, especially even despite being mostly an artist, Samwise Didier returns to voice Samuro, one of the Blademasters that he voiced in Warcraft III. Blizzard, however, tries to avoid Talking to Himself whenever possible, so, for instance, Steve Blum just does Abathur and Rexxar only, not Anub'arak (which created a Broken Base). However...
This is especially relevant in the Latin American version with Tracer, since they used her Mexican voice actress, rather than using an Argentinian one for her.
Both played straight and subverted with Fenix. For details, see The Other Darrin and What Could Have Been.
Screwed by the Network: In December 2018, Blizzard announced that they would officially be scaling back development on the game as well as canceling all related e-sports events. While Blizzard did promise that new content will still be made for the game, it will be significantly reduced. Many fans have taken this to mean that Blizzard has all but given up on the game and is simply leaving it on life support. This is evident when the amount of heroes released in 2019 amounted to around only five, in comparison to the nearly ten the previous year.
Michael McConnohie does Lich King Arthas, Uther, Xul, and Kel'Thuzad. With the addition of Deathwing, it is now possible to have an entire team voiced by Michael McConnohie, and if that wasn't enough, KT and Arthas also have announcer packs.
Patrick Seitz does Crown Prince Arthas, Artanis, Garrosh, and Cho.
Steve Blum does Abathur, The Butcher, Rexxar, and Dehaka.
Michael Gough does Tassadar, Mal'Ganis and Deckard Cain.
The French version somehow manages to top this by having Guillaume Orsat dub Illiran, Ka-Beleth and Medivh, meaning that you can have Guillaume Orsat fighting Guillaulme Orsat while ordering Guillaume Orat to help him.
Throw It In!: Blizzard's goal is for each Hero to have multiple viable playstyles, and when they see a Talent being picked overwhelmingly, they will typically nerf it and/or buff the alternative choices... but not always. In February 2018 they solved an overwhelming-Talent problem for Greymane by 1) removing itnote Draught Overflow: increase the range of Gilnean Cocktail's Splash Damage by 30% entirely and 2) ...incorporating it into the ability, so that Greymane has its effects 100% of the time. They've also done this with a few other talents, such as Double Crossnote increases Discord Strike's area of effect and causes it to hit an area perpendicular to the main strike for Alarak, Chain Bomb for Kael'thasnote Enemy heroes hit by the explosion of Living Bomb will receive a Living Bomb, Zealot Charge for Artanis (as well as an autoattack range increase) note Twin Blades now has more range and allows Artanis to charge in (this was done to fix his blatant range problems)Snipe Masternote increases Snipe's damage by hitting heroes, but the bonus damage is lost if Snipe misses for Nova, The Master's Touchnote hit a number of heroes with Arcane Rift without dying to boost its damage and reduce cooldown on Medivh, and You Want Axe?note increase attack damage by attacking enemy heroes on Zul'jin.
Somehow. So yeah, Nova is pretty hot, so fans do clamor for a summer skin for her, maybe her in a swimsuit or bikini. Blizzard's response? "Here, have Bikini Stitches!" Cue fans desperately looking for Brain Bleach.
The identity of the last two yet-to-be-named members of the original Overwatch Strike team was a long dormant mystery among its fanbase. Naturallly, when Ana reminiscing about them in her Stop Poking Me! quote, their name were given as redacted and redacted.
Ana: I just love this photo of Fareeha and me with the original Overwatch team. It brings back memories of times with Jack, and Gabriel, and *beep* [Redacted]. Oh, and I could never forget *beep* [Redacted].
The Hanamura Showdown cinematic, which introduced D.Va to the game despite the buildup suggesting several other options with Deathwing being the top contender, quickly became infamous among the fanbase for the twist. So naturally, Blizzard used a screenshot of the infamous claw mark on the door to tease Deathwing's reveal on the official Twitter. Judging by the comments, it actually threw people for a loop, leading to a lot of players expecting a D.Va rework.
For a while, the profile screen included a "Coming Soon" notice underneath "Versus AI" alongside the level and league rank information, indicating some kind of statistic tracking for Versus AI matches was in the works. However, nothing came of it; the space was eventually filled with the win stats for Heroes Brawl. The profile screen was later redesigned to include more detailed statistics, including for AI matches, but in a method that wouldn't have fit in the original space anyway.
As noted in this blogpost, Thrall's old kit consisted of Chain Heal, Earthbind Totem, Lightning Shield and Bloodlust, which are all shaman-themed abilities, but fit a Support hero more, which is not what they envisioned Thrall to be. So instead of discarding the kit, they looked up the lore to find another shaman and found Rehgar.
Bill Roper, Fenix's original voice actor, expressed interest with his reveal in reprising the character. Blizzard re-using Marc Graue, the voice of Talandar from Legacy of the Void, seems to indicate their decision to use Graue's voice as the canon depiction of the original voice of Fenix. It should be noted however, that there may be other reasons they didn't contact Roper (such as his being involved in Blizzard North's messy split with the parent company).
