I'll only quit is it's a minute or two into the game and it's completely obvious that the other team is going to dominate my team. There's zero fun in it for me if I'm purely cannon fodder. If it's 8 minutes in and we're down 5k and we're obviously going to lose I'll stick it out for the medallion. But one minute in, enemy controls all zones and they're already up 3k while we have zero kills? Bye. At least when it's only 3-5k that we lose by I can make some bounty progress...
