Because, god damnit people dont want melee, people dont want gay zombie skins.
I wish to know the difference between:
L4D1: Person able to carry two long range weapons and can melee the stuff out of everything with said long range weapons.
L4D2: Person can only melee efficiently with a melee weapon, and thus can only carry one ranged weapon. However doing more damage.
To me it seems like the melee is better in the first one. How would L4D1 somehow benefit this "people dont want melee" demand when you can pretty well meleerape any zombie and special infected other than the tank?
