Yep, I'm doing the same with IS and OpenRDX - different cats, different skins, same effect. I actually ran "For the Horde" with my guild last week - I was 5 of the 6 healers on the raid. It was pretty awesome, killed all four alliance leaders without a single death. This would be ABSURDLY more broken with druids than it is with my shamans... I believe I could use 5 druids to keep 3 players unkillable with lifebloom while dropping 5x hots on anyone who gets wounded.
