I've been playing since the beta dropped and only learned this recently so I'm sure there are others that don't realize. The way your character moves is based on where you are looking, not the up and down arrow keys

How do you guys warm up? I really need advice cause I feel like I play the best after doing an unrated match. However sometimes after I finish the unrated match I'll already be burnt out. So I wanted to know how do you warm up before comps...
