I've played on the ptr and shadow is just not there yet tbh vs. some comps. All my gear is satin with hit and tbh I don't feel like farming up a mooncloth set when I have a resro shaman just about to hit 80. So im thinking of a SoL / mana burn build with my dual spec if shadow don't cut it vs some comps. Penance is still meh vs the new smite glyph in terms of taking someone down.
Im thinking of 2 builds either Focused Will/Blessed Resilience or Focused Will/Pain Supression. Im leaning towards PS since you use it stunned. Comp im using is Priest/Rogue/Shaman. Im not a 2's/5's person tbh.
