Shadebinder Warlock only has 1% usage and Osmiomancy Gloves have 1.6 % usage. So Bingo is nerfing osmiomancy gloves while prismatic hunter sits at 36% usage. More than all Warlock or titan subclasses combined. I would be less annoyed if they buffed any of the other parts of the kit. If I had to guess a dev went up against a mildly competent Shadelock and decided it needed a nerf.
