Hp increased , and also dps . I mean if it was a decent fight vs 1 BT boss (screw his name atm ) now i can burn trough with 1 single vanish and even that almost at the end .
Also mount hyjal . And some older raids . I admit some stuff may be easier with a great energy regen , with higher crit or avoidance and so on .
But rlly 400% health pools or having under half a million makes a difference . Also the dps . imo ...
