Benediction is fine. The CD isn't really that extreme for its purpose. I guarantee if the CD was dropped any all the Scholar mains would cry about it.

I feel your pain for PvP, I really do. However I will probably just Scholar for PvP and WHM for PvE.
There hasn't been a single moment in PvE yet where I've thought "should've rolled Scholar" lol.
I'm sure they will come up with a way to balance the PvP a bit, but I really don't think either healing class needs to be brought closer to the other in PvE. Both fit their niche nicely.
