1- Shaman - Guaranted double crit with elemental mastery every single time
2 - Hunter - big chance of failing fd/trap, in proportions never seen in vanilla
3 - Mage - double sheep happens way too much, even when casts are no synchro
4 - Rogue - Vanish weirdly broken on several occasions
5 - Hunter - Pet responsiveness feels like subpar russian private server
6 - Misc - When dying, if you click fast enough, you can instantly resurrect directly at your corpse
7 - All classes: Counterspells abilities wont work if used at the last second
8 - All classes - If you pull with an interrupt on caster mobs, you will start the fight with interrupting his cast.
9 - Healers - “healing corpse” your heals actually go off and reach target, but he still dies regardless
10 - Warrior - Execute batching and spending all your rage at time of casting + next auto swing, but not doing damage due to batching.
11 - battlegrounds - entering huts and getting berserk/leaf buffs and managing to get out without dismounting
