Warlocks nades were the first ones to get nerfed. Vortex/solar grenade reduced damaged and duration by 50% at launch. Reduced 1 seeker from axion bolt from 3 to 2. Song of flames ability reduction rate was nerfed. Currently(haven't played since jan) there is a bug for ss if you don't have melee charge up then your nades dot wont proc most of the time. Just sayin
