Coup de Grâce nerf? Really?
I mean, this perk only gives you 5 double-lunge hits, if survivors will manage to finish all five gens (if not - even less). Plus, those hits can be easily wasted if you are not careful with your lunges. What's the point of this?
I would understand a change of reducing percentage considerably, but giving it permanent effect for each gen (like Fire Up, for example). But simply reducing percentage without changing the effect is just... I dunno... stupid. This perk wouldn't even be that useful.
Only five chances to use it, I remind you, and the effect isn't even as good as PGTW. It doesn't even really give you any real pressure, unless you are lunging only at wounded survivors. And saving lunges wastes your time.
