AST are naturally faster casters, and the their buffs are to die for. The playerbase is already plagued with so much stupid, even dumber than WoW's healers.
You know how dumb?
We got players Stragetically (never) use any of the good stuff or (never) do anything to make it easier on themselves, even in the long run. They don't even know when to apply a regen on the tank! REGENERATION! ON! THE! TANK! BEFORE ASTROLOGIAN!!!!

And now they can't even do something as simple as draw a card that's off global cooldown, even worse, some act like putting them all on the tank is the hardest thing to do. I'm not saying they should but they are targeting them, how hard is it to just mash the button!?
