Manitou spectres still needs to be buffed in Patch 2.7.7

Gazing Demise:The damage of Spirit Barrage is increased by 100~150%. Spirit Barrage gains the Phantasm rune which lasts twice as long, and the attack rate and damage from Manitou spectres is significant increased.
My Note:Mundunugu performed very poorly when facing single elite or Great Rift Guardian, indicating that Manitou Spectre still needs to increase its damage by twice. Blizzard has attempted to double the damage of Manitou rune, but it is still not enough. The Mundungu set is currently the only new set that can’t pass GR150 in Non-Season, which is unfair and suggests that Manitou’s damage still needs to be buffed.
