I dont think it needs a nerf mainly because if they were to nerf that, the sun singer would have nothing but self res, and they nerfed self res anyways, people only complained about sunsingers because the majority of warlocks used it, now the april update has kind of changed that idk why but i see a lot more stormcallers and voidwalkers these days, thats why people have stopped complaining about them, not to mention, the sunsinger is the only subclass the warlock has that had useable nades, stormcaller has litterally the most useless nades ever and the only time voidwalker nades work is if theyre using nothing manicles with scatter nades and even those are super inconsistant
