Viking Funeral and Touch of Flame are bugged, so they actually decrease the amount of damage you deal (video proof can be found pretty easily on the forums). Solar Grenades appear to have secretly had their damage reduced and number of ticks when burning also reduced. Firebolts lost range, arming time and a large chunk of their damage. Angel of Light is and always has been terrible and Sunburst is not worth using over Radiant Will. Double Fusion Grenade is the only build that grants any kind of success now, but seeing as you haven't done anything considerable with your Warlock since the beginning of last month, I take it that you don't know.
