* AbridgedArenaArray[=/=]AdaptationDisplacement: Many people play ''VideoGame/WarcraftIII: The Frozen Throne'' [[JustHereForGodzilla just for DotA.]] ''VideoGame/WorldOfWarcraft'' notwithstanding.
** Also, this wasn't the very first ''[=DotA=]'' version ever made - it's just the most popular (and most frequently updated). As to comparing it with other versions of ''[=DotA=]''.
* ArrogantKungFuGuy: This is a MOBA.
* BaseBreaker: Deny. Either part of the metagame that people should do, or a ScrappyMechanic that encourages the "Make the game as unfair as possible for the other team" mentality.
** There are *lots* of mechanics that fit into this category, usually mechanics similar to denials that were either bugs, or unintentional side-effects of the ''Warcraft III'' engine. Most of them are kept in because the devs and lots of players believe it adds skill, but many still believe they're arbitrary.
* CatharsisFactor: Got trashed in a legit match? Start a single-player game in a bot-available version, select the heroes that just kicked your (team's) ass, turn on God Mode and kick THEIR asses.
* ComplacentGamingSyndrome: To the point where some skilled ''[=DotA: Allstars=]'' players have some degree of difficulty playing in Ladder.
* CrowningMusicOfAwesome: as of version 6.60, "-music special".
* EarWorm: That Scandinavian ''[=DotA=]'' song.

*** It's actually a song about how someone loves [=DotA=] more than his significant other.
* GameBreaker: Item pooling. Recently [[{{Nerf}} nerfed]]. Also backdooring (no, not THAT backdooring) and cutting off your opponent's supply of creeps (the latter is debatable). The Fun Tavern (only available in versions where you can team up with and battle the AI) reveals that some heroes of past versions were even more broken.
** Backdooring was never a gamebreaker. People just didn't like it.
** A lot of items can be game breakers if you manage to get them early enough in the game before everyone else is buff enough to handle them; some particularly nasty examples are the Armlet of Mordiggian, Diffusal Blade, Guinsoo's Scythe of Vyse, and the newly buffed [[VideoGame/TheLegendOfZeldaALinkToThePast Agahnim's Scepter]].
** And, historically, a number of heroes have been this, due to the honest mistake of being overpowered when they were introduced. For example, the Moon Rider (whose BeamSpam has already been described) and the Sand King (who, come to think of it, can still stun you / slow you / shove his tail up your bum for the win, just not as quickly), but undoubtedly there have been others both before and since.
*** Also just recently, the Tauren Chieftain and the Batrider with Radiance... and a little before that, Kunkka.
** Phantom Lancer, or as most people call him "Phantom Cancer" is a hard carry that only needs 4000 gold to be end game, can push all 3 lanes without risking his own life, oh and did we mention he has a great early game escape thanks to doppelwalk, which doesn't even clue people in to the fact that he switched places with a fake until the illusion dies?
* GermansLoveDavidHasselhoff: This is the biggest multiplayer game in the Philippines, much like how Starcraft is popular in Korea.
** See EarWorm above - they even made a song based on [=DotA=]. You know Basshunter? That was one of his first hits.
* GoodBadBugs: [=DotA=] 2 Beta once had a bug that allow [[{{Griefer}} spectator]] [[HilarityEnsues to control bots]]. Thankfully Valve fixed this.
* HellIsThatNoise: "FOR KHAZ MODAN!" is either this, or MostWonderfulSound, depending on whether or not the source is on your side or not.
** The distinctive roar of a Mask of Madness being activated after being charged by a [[CrutchCharacter Spiritbreaker]].
** [[LargeHam "OUR BRETHREN'S TOWN IS UNDER ATTACK"]]
** The sounds of ''any'' enemy [[InvisibilityCloak windwalk]].
** And more recently "THE ENDS JUSTIFY THE MEANS."
** AHHHHHHHH FRESH MEAT!
** In [=DotA=] 2, SILENCE! SI-SI-SI-SILENCE!
* {{Griefer}}: [=DotA=] has a ''terrible'' problem with people who leave the game. It's slightly nullified in that if someone leaves, the game is declared unfair and lets other players leave without penalty, but this usually just makes the situation for a losing team ''worse''.
* ParanoiaFuel: The Night Stalker's story indicates that he is supposed to inspire this in others. On the meta level, a good ganking team can make the other side afraid to leave their base for fear of death, allowing the carry to farm in peace.
** Of particular note is the Stealth Assassin. Have sharp eyes, because he has an InvisibilityCloak and more often than not can BackStab you to death in under three seconds (So does any other hero with an invisibility ability).
** Miss mid/nh nh nh nh nh nh nh nh nh nh...
*** Bloodseeker.
* ScrappyMechanic: Same Hero, Only Mid, and the server chooses Lord of Olympia / Warlock / Goblin Techies. What fun.
** Also add All Random and No Powerups, among others. The former is usually only played with friends; anyone playing the latter is "automatically" a {{Scrub}}.
** What happens if someone leaves? They trash the whole game.
* {{Scrub}}: Most players starting out play like this: either their attitude improves or they get worse.
** Usually they get worse first, due to finding some league/tournament rules, afterwards some of them get the attitude improvement.
* StopHavingFunGuys: [[RuleOfThree This is a MOBA]].
* SuffersNewbiesPoorly: Both in terms of the gameplay AND the player base. It doesn't help that if you play poorly, you ''will'' bring your team down by giving lots of gold and XP to your foes. If you do, expect cries of 'noob' and people demanding you to kill yourself.
* TheyChangedItNowItSucks: (Almost) Anytime a remake of a skill or hero occurs, even one that allows the "victim" to become competitively viable, someone somewhere will cry foul.
** There's still some noise being made over Valve's remake as well.
