This is a bit nice. Let me explain why:
As already mentioned, it gives a bonus to healing from everyone, that's including SPs. You can apply this buff as a shaman using chain heal (or as anyone with grp heals) to pretty much the whole raid, which cannot be sniffed at. Also, use your r1 healing wave (or class equivalent) to stack up the buff 5 times in about 6 secs then do some heals, which will keep the buff stacked for ya. Granted, in 10 men instances you're only gonna be having around 4 people healing the tank, max-- dru's hots, maybe 2x healers sharing the duty, and mebbe an SP in the tank's group. But even with a maximum of 4 healers, that gives a hell of a lot of extra healing. The 5 stack bonus is 150 healing (I know it says 5x20, but hover over the buff and you'll get 150). Now, multiply that 150 by 4? That's 600 extra healing OVER 20 SECS! Guys, come on... this is crazy, even if just 2 people are giving heals to the tank.
