I quit in Wrath and came back in Late Cata. I found every single class has the same spell with a different name. I.E Rip / Rupture. Ferocious Bite / Eviscerate. Sprint / Dash. etc etc.
What's wrong with a bit of differentiation? So warriors are better interrupters than us, they can do the interrupting in PvE then can't they
Where one class fails, it should succeed elsewhere is my view and THERE SHOULD be classes that are much better than others in certain areas, but this is all just my opinion. Ya'll can do w/e the f*** you wanna dooooo! (HodgeTwins!)
