2 things I'd add:
- poor range, which becomes especially noticeble in laggy environments and adds to the 'hitting while moving problem' (I'm pretty sure they can fix that and improve range of weapons quite simply - check the shadowdancer epic Moment - the tech behind this seems to be there)
- on click attack offhand procs only work while in the attack chain (if you use on click attacks like anvil of thunder you only get an offhand proc while standing still, if you move and use it you only get the mainhand proc.)
