Fists of Fury channel while moving and adjusted to a point where it feels more like a spec defining ability and not something that's barely a DPS increase and only then if you make all the right choices about it. I don't dislike that FoF requires some skill to use at the correct time; to the contrary, that's my favorite part of the ability. I just wish that A) There was more of a reward for that sort of good play, and B) That there weren't situations like Bloodlust where Fists of Fury just is totally neglected because using it would be a DPS loss. It's our defining* cooldown, it feels weird to eschew it in our highest damage phase.
Those are my two big things.
*Whether or not FoF is a spec-defining ability is up to debate. :P
Agree another "good on paper" move that just didn't pan out well, just like Touch of Death.
Although killing someone in it in pvp feels awesome.
