I just don't like samey skills. The only skill in HW for Ninja I care about the most is just Armor Crush. Enmity control is for bad groups or to let the Tank DPS more. Or give a overzealous healer or a guy who doesn't have quelling strikes take a chill pill.

I do find it interesting that both NIN and DRK for their lvl 60 skill both are quoted as using a 3 fold attack but only Ninja's hit 3 times. They really need to be more clear with these tooltips.
