Because crouching vs an AWP is bad, you are slowing down you movement speed.
It isn't faster, you can both crouch and counter strafe at the same time, it's all about choice, if you think the opponent is pre aiming the head, you crouch peek.
I'm supreme, but notice how you are changing the goal post. You said it was easier to headshot someone whole moving instead of hitting that AWP flick to the body. Yet you provided 0 reasons for that.
And again, I already said it. Awpers are going to be less or more aggressive depending on trade potential, if they have a clear 1v1, they will hunt it. Awpers won't take 1v1 brainlessly because if they get traded, it's bad.
