I know its a while away yet, but that casting while moving thing, its only 10 seconds, but you'd only need to be standing still for the last second for it not to interrupt. Are we gonna get a bubblehearth abuse that the pallies get?
not to mention casting res on people in pvp :>
this and haste stacking could allow some seriously funny stuff (until patch 4.0.1 when lifegrip and casting while moving are replaced by +1% healing).
