Except that warriors have no mobility and can be cced and blown up by the enemy group regardless of "regeneration and mitigation." And 7.5k? We're talking about seal rock right? And without battle high?

Cmon now. And to even get a 5k plus fell cleave you have to use all cool downs and some dps had to be silly enough to stand still and eat a storms eye and full swing and wait around for the fell cleave instead of just running away.

Exaggerations.
