I think it's ok atm, it does ignore the damage penalty from Defiance (which I never really realized until I re-read the tooltip 1 week ago >_>), decent damage, aoe around you instead of a cone, it doesn't cost any tp, looks badass, generates hate and it's instant. Used it quite a lot during my leveling to 60 because others kept joining with full i170 gear which was tough to hold hate at some points (especially vault).

I wouldn't say no to an additional aoe bleeding dot debuff, that'd sure make it more enticing to use for sure (and it would fit the brute force theme WAR has).
