The math was just not adding up to how much this man was healing, and the healing was happening irregularly. It had DragonClaw,PD, and Red Buff so we would end most fights fighting 1v5 where he would be healing to full from 10 HP.
Renekton 3 heals 350x5= 1750 HP per Q
Renekton 3 had 2160+200(Redbuff)= 2360 HP
My singed was alive every single fight applying the Morello debuff and he was still healing to full every single fight.
