Glyph of Dark Binding replaced with Glyph of Focused Mending
Glyph of Focused Mending
Causes your Prayer of Mending to only bounce between the target and the caster. Major Glyph.
The new glyph probably doesn't work when PoM is self targeted which nerfs Shadow Priest self survivability.
When will Blizzard stop nerfing Shadow Priest solo capability to nerf Shadow Priests in arena?
