The new Herald elite spec for the Revenant is getting a shield, the shield skill 5 is a 3 sec invulnerability (they heal while channeling). Churning earth with a 3.25 sec cast could be cast right after you see a revenant uses this skill. should finally be a good use for churning earth in pvp. and they even get a trait to proc that shield skill at 25% health, and even if they cancel their cast, they lose healing, so we had a use for churning earth to scare them out of an invuln.
so instead of concentrating on how kitten the tempest is, why not think about how awesome our current builds are going to be vs other classes elite specs?
