These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Creator Worship: Not to cult-like levels, but the dev team has been very, very open and communicative about the game's development, including going into the rational behind potentially unpopular stuff such as Money Sinks, and actually listening and responding to suggestions and concerns. The fan base has reciprocated with appropriate levels of adoration for this unexpected honesty.
Creepy Awesome: The Mordesh, to their fans. Just creepy to most everyone else.
Fandom Berserk Button: DO NOT, under ANY circumstances, mention ANY similarities to World of Warcraft. Even if you mention having fundamental genre traits, mentioning them will usually cause people to flame you. That said, some people have made a few jokes - such as calling the dominion "The HordeIN SPACE
Given that the game was called "WoW killer number seventeen", and very few games of this genre maintained a consistent playerbase above a couple thousand after the first year (sometimes even within a few months.) it's only inevitable that some players are waiting a few months to see if the number of players logged in simply aren't simply playing Wildstar as a "One Night Stand". To be fair, this happens with a lot of online games, and has happened so much people are feeling apprehensive.
The fact that the game requires a subscription fee makes some people even more apprehensive about trying it out - the game is $60 right out of the box, and on top of that wants you to subscribe. As some people have described it, only World of Warcraft is able to get away with a $15/mo subscription fee. Others find the subscription fee passable, because it keeps from "Microtransactions", a feature that is very easy to become a Scrappy Mechanic.
The Stormseeker Pell. You unintentionally deliver poisoned supplies to them, killing them all. You played with their children. You helped them with their chores. You earned their trust. It's one of the first missions in Ellevar, so pretty much any new, uninformed player will do this quest arc.
On the Exile side, there's the fate of Deadeye Brightland's family, wiped out by a dominion artillery barrage moments from getting away to safety. They were going to name the kid after you, too.
Drusera's village of critters. After help construct it, the Entity proceeds to destroy all of it.
As an Exile, having to kill Lucy Lazarin after she is infected by the Strain
Scrappy Mechanic: Mashing F to escape stuns was considered very irritating, and was eventually replaced with a different quick-time event where the player has to hold down a specific movement key for a period of time instead. The newer system was much better received.
The Woobie: Victor Lazarin's unlife suuuucccks. It all started when he accidentally turned his entire race into zombies. About the only people he cares about who HAVEN'T died yet, including Elderroot, are the Aurin Queen, a player character who advances the quest lines, his daughter, Lucy, and his Chua adversary, Mondo Zax. And then later his daughter is infected with the Strain and has to be put down, comfortably putting Victor Lazarin on a list of people the universe just plain hates.
