They should rip the “Increases Drain Life healing by 30% while your health is at or below 35% health” from Death’s Embrace on the affliction tree and make it a baseline passive for warlocks with one added change to it. Make it snapshot the healing boost. “If you use the drain life spell at or below 35% health your drain life will heal for 30% more.”
That is the first step. The next step is to have its damage scale with our health pool. Drain life would now deal an additional 3% of our max health as damage. This means unless the target has damage reduction popped, drain life will at minimum heal for 15% of our maximum health. I think this is a fair change but balancing would of course be considered.
Also remove soul rot functionality so that this doesnt become op as affliction ok its fixed now.
