Now don't get me wrong i don't want to see a WW witch doctor... But how about a weapon that gives manna for each crit hit? (Instead of mana per second) Passives and weapons are what feeds those builds for the other classes. I'm not familiar with monks/demon hunters but it would be nice to have something that helps us replenish our skill cost, so that way were not on clean up duty always.
Also, I know there are ZD builds.. that can make a WD arguably more OP than others but go ahead and price check the cost of a ZD WD build to a CM wiz or a WW barb - not even close.
Again I don't know much about the DH or Monk but i'msure they could benefit from this as well
