It's fine, no nerf.
NO!!!! Its a freaking molotov it should be a one hit kill!!!!
Unless their wearing armor
I fail to see how wearing TLOU armor will save you from burning liquid.
It depends what is regarded as a nerf to molotovs. Molotovs are a problem currently - I really have no idea how anyone could deny this. They are a problem primarily due to their availability and how effective they are with the explosive expert booster.
Reducing their availability and removing Explosive Expert 2 would be the best bet, in my opinion. No idea how anyone could think the status quo is fine though. The worst solution would be to actually weaken the molotov itself. They're about right until you add in the fact you can get so many and the fact that you can make them so much better with the perk.
