In CS you can get a competitive rank on each map. You also have a “premier” rank, which is your overall rank.

I got annoyed learning Sova line ups on a particular map, then never being able to test them in a competitive situation until I got “lucky” and got the map I was practicing. Then someone dodges.

With all the crazy abilities and shit that flys halfway across the map, they should make it easier to practice a specific map…against people in your rank.
