Why fists of thunder. We already have the relatively useless fists of wind, might as well fix that before putting more fists in.

Same goes with the idea of fist of thunder aoe. That's just a band aid for the fact that arm of the destroyers is kind of garbage and both arm of the destroyer and rockbreaker are massive TP drains and Howling Fist has an absurdly long cooldown for what is essentially a slightly stronger rockbreaker effect.

Don't clutter the monk, fix what doesn't work first before adding in more crap.
