Just playing around on testing dummies and noticed they nerfed Drain life's spell coefficient.
Last patch on 80 dummy I was doing 3.9k ticks with drain life in full rotation.
Now I'm only doing 3k ticks.
Sidetrack: the immo change has a huge effect on the dot at least as demo. It's gone from doing about 1k per tick to just under 1.8k per tick. Haven't tried destro yet.
