Confirming what we already suspected, devs think shadow dps is fine:
In the case of shadow priests, we thought damage was a little low and made a very small adjustment. [i.e. The twisted faith/improved spirit tap buffs.] Many shadow priests think their dps is still unacceptably low, but we don't agree. (That also doesn't mean we won't make changes in the future. We do change our minds.)
I want to meet the person who says it's fine. Not to shout at them (although that would be my first instinct) but to try and learn from them. Logic says Blizzard knows the game better than I do, so when they say dps is fine it probably is — in theory, even if we don't see it in practice. Knowing how Blizzard conducts these tests, and under what circumstances, would be hugely informative. Do they play the class in raid situations to do the tests, or are they based on mathematical models? What tactics do they assume for each situation? Are they lumping AOE capability in with single target? Do they factor in stat variations, buffs, debuffs, lag, frame rate, what skill level do they balance around? How do you even quantify skill level? So if you have any contacts at Blizz, please drop me a line.
