Instead of deep holy go 30/31/0 or 31/30/0. Discipline is, obviously, great for PvP but it would be cool to try it out for PvE. I played a Disc priest in 25 mans for a bit, and it was fun. Power Infusion (though badly nerfed) would be interesting to try in a rotation of 5. Be sure to post if anyone does this, I'm curious.
