Its not a bug.Angry Grimace said:The answer to your mastery question is that you don't actually acquire any masteries benefits until you acquire gear that has mastery rating on it, plus you have to be level 75 to train masteries in the first place. That might be a bug though.
The only gear with Mastery rating is Cataclysm gear(any quality).
When they set the training level at 75 you could quest in Cataclysm zones at level 78. The minimum Cataclysm questing level has since been raised to level 80. If that is for beta testing purposes or not is yet to revealed.
Not really. Exorcism is classified as a spell which means:Retro said:Exorcism early on is completely useless except as a pull, but once you get the Art of War talent it becomes sweet, sweet candy...
higher spell hit(17% instead of 8%)
lower crit damage bonus(150% instead of 200%)
does not proc seals(only melee attacks proc seals)
And this isnt taking into account the nerfs its getting in Cataclysm.
