Ghostcrawler on Dots, hots and haste ( Source ) We are trying to make haste a slightly more attractive stat for classes that utilize a lot of damage or healing over time spells, specifically Shadow priests, warlocks (though especially Affliction) and Resto druids. We realize other classes use hots and dots too, but I think we can all agree that it’s a bigger problem for the ones I mentioned.

The rest is here:
