Team ups 1.10 Rules?

Good idea, and just incase a member of a certain team is not present, there should be a backup to play their character, so they won't get too far behind. Or possibly a few backups? Maybe like 24 or so people per group (3 people alternating with 1 character). Of course this leads to account sharing, and trust issues, which is another good reason it should only be between trusted members of Zelaron.
