Just had a quick look at the ptr patch changes for 5.1, lots of new intresting features for a few classes and a few nerfs. Shadow Priests however look right now as if they are being left alone, this would be good if we were not in need of a buff. DPS wise we are never going to be top not in the current state, and in my opinion we lack a burst button.
Rolled a shadow priest for MoP because id never played one at a high level, the skill level to play a SP is significantly higher than some other classes, and I enjoy that but I would really like to see some form of buff before 5.1 is released, any thoughts?
