I won't say that. Right after reaching 120 I went to Kabraxis and killed him easily with TU gear, Quov Tsin was a joke too( but he is a joke to every sin xd). Clear speed in rifts can be really good even after nerf.
It has few really annoying disadvantages(mana sustain, problems with catching running targets, not many mods working with skills) which became worse after patch but still doesn't suck.
