I see your point fully its true 33% up while able to still tank is good in any situation. But the problem lay with the skill itself it beggs what are we really getting with it .

Duration 10sec on average thats a 4 move line with current attack speeds that means casting unchained then cycling all the attack buffs to include infuriate you get at best 2 hits at maximum 3 if you add an infuriated move . Mind while performing this both healers and dps have cycled 3 or 4 rotations and bult aggro/hate so on a team standpoint does this skill really warrant dropping a hate building move for? Are we really doing the job if were dropping hate for damage ?
