Yes because more damage (which means more threat) is just what we need.But it looks like the generic 2 piece bonus is 20% more damage for everyone.
I am not unhappy with these tier bonus's but comparatively, I don't think it really stacks up. Of the other 3 tanking classes 2 of those get a flat damage decrease for abilities on a 1 minute cooldown, and the other gets a shield that is going to scale the better gear they get. 12% dodge versus 12% less damage, oh shoot this boss does magic damage- guess i'll respec ret or holy for this fight. But yeah, 1 minute cooldown dodge trinket is nice. Especially for trash.
