Give the pug a glider PVP option. So he or she can glide their way into endless losses, come back six months to be ranked up.

The premade can continue to stroke their epeens (they do not even have to know they are playing against bots) and for most it would make no difference anyways, and then everyone is happy !

This would get rid or your AFKers too. It they are gliding, then they are at least contributing.

Problem solved with a little creativity.
