I do think it promotes team play and builds class skills. With a team comprised of each class it's ok. Two mages is painful because they can just cycle curse and your dead. In general this shouldn't replace tdm or ctf. I would keep kdr out of it permanently and make people earn their aps the way everyone else did, the hard way. It makes a good training grounds where people can learn and not have it count against them. Can do leaderboard and awards but not aps/kdr.
