The one thing that I'm still very frustrated with is the evade issue. This seems to happen to me far more frequently than it did pre-Wrath. I hate it when a mob resets just as it would die, particularly when it's an elite. It always reminds me of Jester diving below the hard deck. I have nothing to do but try to kill the mob again or move on to another one that's (hopefully) not evading.
Over all though, I'm happy with Wrath of the Lich King. There are some dreadful quests, but some awesome ones as well. A lot of things are reused, but many are new as well. I'm over being mad and back to enjoying the game. But Blizz, if you're reading: please stop the mobs from bugging out and going home.
Now readers, it's your turn: Do you forgive Blizzard yet? What will it take to make you happy with WoW?
