I'm starting to feel that I am decent in this game. I still make mistakes as surviour but I get along. I am pretty good at putting ambushes as a boomer and I can get around playing a smoker

But what's wrong with the hunter. I can't play with him. I always get stuck, I can't aim, I can't pounce. That wall jumping thing just doesn't work for me.
I don't know what to do as a hunter.
