Monk:

Remove haymaker and replace it with One Ilm Punch. OIP now inflicts 20% slow and is on 30 second CD and has 150 potency (no TP cost obviously).

This will give Monks an actual slow that can be used while weaving skills through their rotation. It removes a useless skill and makes a cooler sounding and looking skill more useful.

I stand by the Fist of Wind change too as it will give Monks more options for more fights. Specifically in T8 where the dmg may not be as useful as the sustained TP.

A lower CD on Perfect Balance so we can get greased lightning up faster after one of many boss transitions (I'm looking at you Leviabeetus). Or perhaps leave PB and just give us Axe Kick as a PvE skill that is on a 180 second cool down as well. Axe Kick gives 3 stacks of greased lighning automatically for all those wondering.

Essentially it will give us better sustain and more options for weaving.
