A thread for the bugs found in 5.0.4, maybe somebody could post them on the US forums.
-Chaos Bolt's damage is delayed. It occurs some time after the animation hits the target, which is VERY frustrating and might cause problems and put us in a disadvantage.
-Shivarra's Mesmerize is interrupted by Lesser Invisibility when not in combat. This is due to the fact that since MoP, Blizzard allowed the succubus to use other abilities even when seducing, without needing to manually stop the seduction. Although it's good for when you must Whiplash, it is inconvenient when your succubus is out of combat and engages through a Seduction. Please don't let Lesser Invisibility overwrite it. And no, putting up Lesser Invisibility wouldn't be a good option, it's too much of a hassle. Putting up armors was removed, so the same policy should be followed with Invis, which is much harder to keep track of.
-Shivarra's Fellash has severe delay and bugs even more than Whiplash. The delay is so bad that sometimes the target will have to time to cross one side of the circle, thus allowing it to be pulled to the opposite direction (so make things worse for you rather than helping you).
-Dark Bargain's effect persists even after a duel, causing the warlock to die if he is at low health.
-Shadowfury also bugs from time to time and doesn't stun the target while they are on the move.
-Havoc no longer effects targets that LoS, even after they are in line of sight.
That's all I can think of for the moment.
