We could just say this, instead of the 3 out of 4 idea or the single nation idea:
In order for a human team to win at least one noob must survive on the winning team. This would provide that incentive for team captains not to ignore their lovely noobs (not that they would) and put an effort into leading them and helping them stay alive and also make it possible for a team to win with 1 or two players left alive.
In the event all 8 noobs are completely wiped out or concede, which is what the above rule attempts to avoid, the winning team (aka last team standing) would need to have at least 1 intermediate player left alive for a team victory.
This works for me, of course I'll go with whatever the concensus is though.
