I beg you, for the love of all thats holy, stop tier 1/2/3 players from being able to join tier 4 servers. Or more realistically, at least allow pro spawned servers to be setup to only allow actual tier 4 players in.

I dont know if they have nowhere else to play (not enough players), dont understand that there are tiers and just join any server they fancy, think they're better than their assigned tier or just plain want to be irritating by going and ruining tier 4 games, but lately the situation seems to have been getting worse.

So an option when spawning a server to stop this would be greatly appreciated.
Thank you.
