I was thinking about that. Aspas is Aspas, Cortezia has one of the best aiming I've ever seen, Xenom has immense potential, Nzr is an IGL with a lot of aiming.
If I put it in pure potential, it would look like this:
Aspas = Aspas
Xenom < Kingg
Cortezia > Tex
Nzr > C0m
Artzin < Mazino
In this case, the only weak link would be Artzin, and in my opinion, Artzin is a great player.
