Melee haste adds jack crap at the moment, supposedly they are making it more significant.  HOWEVER when you look at white dmg (auto atk only) its very minimal at best.   Auto attack i probably average 500 dps.  With skills i average 4-5k.  So with the haste change i might do 4.5k-5.5k.

Looking at your gear, id recommend dumping some of your con/dex and maxing INT as far as raw attributes go.  I know you said without losing hp.  Also im not sure of the stats but i thought sandstone was the t5 rare world drop (aka worse then crafted).   

Overall you look fine, id say use aum kor if u have a shm/clr in the group and youll see a big increase in dps.

I am still looking forward to testing out the haste changes, if it is decent don't forget the extra secret procs as well.

I also hope that it will help make a bigger difference between dragon monks and harm/drunken (due to their proc), as well as hand to hand monks vs. two handed weapon monks.  Maybe even to the point where a hand to hand monk would invest more into haste, making us slightly less burst dps (which is how I would describe all current monks at max level now) and more sustained DPS (which is how I pictured Dragon monks, with their additional large damage end attack, and decent dot and proc to keep their damage high throughout the fight)
