Perks Xp rate are unbalanced.

It's too hard to level Berserk compared to the others. It's much easier to do damage with guns (support) or to do headshots (sharpshoter) , or to heal (medic) . To be effective , in fact , everyone has to do HS ; so that sharpshooter thing is a joke.

Sharpshooter is tough to level, yeah. But I find the rest are easy and balanced. You just need a better melee weapon to level Berzerker faster. Trying to do it with the knife or machete takes a long time because of their damage.

I only play suicidal . I can't get to Chainsaw. it makes no sense that you have to play at an easier difficulty to get more xp. In RPG it's the opposite.
