Excluding champs primary role being supp for obvious reasons. I also think game time is a big factor so just apply to a average game being 30-35 min. My best guess is probably a tank like zac. And if you look at lane it will probably only be top or spam ganking jgs, To be clear i know that no non supp champs will be optimal at all on 0cs,would just be cool to see who could be the best
