Glaives had already been nerfed hard, with roaring flames no longer boosting their melee damage, and now synthoceps barely providing any boost at all its caused a lot of backlash. Nobody thinks this nerf was warranted especially since the leading reason was the winterbite exotic glaive. The payoff for risking being in close quarters with a glaive was doing high damage in short windows of time, before backing off or getting stomp one shot etc.
