I would love a patrol pvp map, and I LOVE The low level call high level thing. Make it a special bounty, or try it out as a weekly event where low level players all have to start out on mars, but they can call 20+ players for help. As a 27 defender titan I would love that. Soo much could be done with patrols if they would just experiment. Maybe for 1 week a month 1 map has 2 bosses in each zone (super high level with 4x the usual health, damage, and tons of smaller enemies). It takes 6-12 guardians to take them down. Also make extreme challenges and leave it up to the community to figure out a solution. But don't nerf whatever they come up with. Then after a week or two take it down and come up with a new one.
