So far. Psychic Link was buffed from 35% to 45%.
Next Round of Tuning. It is getting buffed from 45% to 60%.
So… I think we will see a nerf from 60% to 55%. Then when the raid comes out, if there is a spread cleave or council boss, Shadow will Out DPS everything.. then it will get nerfed from 55% down to 40%, possibly 35% again. Then Shadow will underperform until the next patch… where Psychic Link will get buffed again.
