It's going something like this. "What if X?" "X cannot be" "Yes, but what if X?" "X cannot be!". Having a thought experiment about something impossible or unfeasible can sometimes be entertaining, but you need to know that you're engaging in meaningless blather.
EDIT: Oh, and eventually it would stabilize at either a Rock-Paper-Scissors or a Single Best Teamcomp type of situation. Once someone finds a counter to the best teamcomp, either it is the best (because it beat the previous best) or it beats the best, but loses to a different strat which the previous best defeats, leading to a rock-paper-scissors deal.
