I'm glad mouse wheel is used for selecting weapons but it'd be REALLY nice if I could flip the direction for it, I want to go to the right with down not up. To that as well, when I was trying to change buttons the second I pressed to change a key it would INSTANTLY set it to left stick or left stick up no matter what I did, trying to change run to shift was a massive PITA.

I second that - I'd like "mouse wheel down" to be bound to "next weapon", not "previous weapon". Of course I don't want it to be the default and only option. I'd like it to be a choice.
