I dunno, I find most tanks I +15 with greatly values the healthstones(especially non VDH), aoe stun, and brez. And in the case of certain mobs, the curse of weakness.
If anything, what needs to happen is a 5 target cap for fire mage and a target cap for Starfall(with compensation buff to starfall at lower target counts since it is trash outside large pulls and stupid strong on large ones). MM just needs damage nerfs, ridiculous how a ranged spec that mobile is doing this kind of damage. Hunters should never top DPS unless they make one of their specs hardcast stationary 80%+ of the time.
