Only for a week or two more. Whenever priests become solid in any aspect of the game you can guarantee nerfs will come quickly. Disc/Holy is getting nerfed to hell next mini-patch. Heals are losing power, penance glyph is changing from -2secs off cooldown to +5% crit (good for my offspec, bad for PVP disc), fear will break easier and blind + fear will share DR and I'm sure I forgot something else as well.
To be fair, Fear and Blind should've always shared a DR and that is coming from a rogue (maybe it's more my druid-playing side saying that ). The combo of a priest landing a fear into a blind > sap is too strong.
I'm planning on waiting at least two weeks anyway with finals being all of next week so maybe I'll see how everything pans out before I decide.
