Alright so my Proposed change for the ULT is to keep the passive, and adding that his regeneration increases by (1/3/5)% percent for nearby marks when off cooldown. The damage forr the active will e single target and function like Darius's ult in power, but still working on scaling 50% current health cost, and detonates marks on target. Again damage and scaling still being balanced around. Keeping the heal and doubling if target is killed (Effectively 25% heal if no kill, 50% if kill)
