Actually, Paladins still have Flash of Light. So AoW is affecting the mid-range heal. Sure, we don't know how much we can do before we run out of mana, but... DAMN is anything+4x Rets looking good for Cata.

Also, looking at the Necrotic Strike that's currently in beta... 4x DK's will be able to completely shut down ALL healing on a single target.

<---Super excited.
