Not the lowest but the pve community is up in arms. They dislike the fact that Surrender to Madness is the only viable talent and that all the talents in the talent tree are all revolving around that ability, that can only be used for 3 minutes then you die. Legacy of the Void and Mindspike are garbage and completely unviable. Legacy can be used in Mythics because fights don't last long, but is absolute garbage in raids. They don't like that StM is grossly overpowered for 2 1/2 minutes of a fight and then you die, then be complete garbage for the rest of the mythic/raid.
Most of the pve community wants it reworked or removed entirely while wanting bigger buffs to the other talents to give them more viability and talent choice control. It's fun to use at first but having more eye opening negative side effects like being forced to be mediocre dps for 10 mins when it's on cd, one misclick on your rotation and you're dead, the other talents are shit. It's a double edged sword that people aren't happy about.
