ok what about this... make a new town in the middle of nowhere... like the size of athen or something, with all the buildings and all... one side have a grid/whompa/save/reclaim/shops/guards for omni. on the other side exactly the same for clan. flag on each end (one omni, one clan), like CTF but in big scale, all the clanners whompa in, charge omni for the flag, omni do the same, whoever owns both flags gets town control.
with whompas from both sides it would be no trouble getting forces together to come back. would be great fun and a nice big pvp zone without having to worry about getting gridcamped and killed in 2ho, or zone huggers in MMD
also i say like athen because its got a big wall around it make it so u cant run in/out of the town, cant whompa in combat, only access in i the grid/whompa
