The issue with that is that you can't really define 1st team player. And if you try to, there are always gonna be loopholes to argue that someone isn't a first choice player. I also think "international" is too broad of a term. Jack Maunder is technically an international player, but he's also only 20 years old and 4th choice 9. Are you really gonna place restrictions on him? I dunno, I agree that something has to be done because putting out a 1st choice team is not in the spirit of the comp and it's also damaging to players that are gonna be playing even more games per year than they already do, and some people seem to think that putting out a 3rd/4th/5th choice team isn't in the spirit of the comp either. I'd be happy with simply implementing an Under-23 quota.
