People hate because they like to and if we don't say anything SE won't change anything. SE has buffed WAR, nerfed bard, are implementing the vote to kick feature, buffed dungeon XP, and more because of (at least partially) forum complaints.

Basically hate about the game and players in the game is found on any official game forum site. There's some positive too, just much less of it. There really is more hate than usual on the forums now too because of things in 2.1 like high housing prices, loot lockouts, and job nerfs. So all this hate you see shouldn't be surprising.
