The complete list at MMO-Champion is very, very long. Luckily for me and my current leveling project, Draenei Warriors (and indeed all warriors) got off light with a couple of minor bugs. I doubt my level 62 warrior (or any of my 70's) is going to be fighting Landslide again anytime soon. But Priests seem to have several bugs, every class got a few, and the environment, quests and npc sections of the list are quite beefy.
Also, rogues seem upset about the changes, if you follow the forums. While that's probably not a bug I though I should mention it anyway as an issue with the patch.
How's Patch 2.3.2 been treating you? Good, bad, or had you even noticed any differences?
