Honestly, the issue is more that our baseline healing is absurdly powerful. They could probably slash all our healing potencies in half, and we would still be able to get away with DPSing the majority of our time in most encounters.

It's a bit sad, because as Ultimatecalibur mentioned, it doesn't really give us the chance to utilize the full suite of healing spells. Though I'll admit, most of the actual GCD kits aren't terribly interesting to begin with, so it's not as if I'd like having to turn to them in their current iterations.
