bad design.
it just homogenizes fighter strength.
big band isn't a healer/sustainer.
also gives him a futile resistance on steroids which is bad design.
futiles been nerfed like who knows how many times now.
nobody likes facing it.
if it were just the heal alone maybe maybe i could accept it but the % of his own health dmg being dealt to enemies who attack him makes absolutely no sense and will just make fighting him impossible if he has any supports,allied buffs,pf or rift modifiers and catalysts.
