theres should be a map made especially for battle! there should be arena somewhere on the map. a HUGE arena. there could be many arenas. one just for 1 on 1 combat (non-multicombat arena), one with multi-combat, one that has two portals in front of it. you cant just walk in the arena. you gotta go through the red portal or blue. red portal puts you on the red team. blue puts you on (suprise!) blue. then there could be like a lil newbie arena for low lvls. there should also be a small town with shops that sell only combat based items. rings,fighting books,summoning books, armour,weapons,potions, and tickets to go watch the carnage from a safe place! (only for the huge arenas) tickets should be a bit cheap. about 100gc each maybe, and when you use it it teleports you to the bleachers or benches that you watch from.
I think the map should be called the valley of conflicts
