ArenaNet:Guild Wars 2 suggestions/player made friends only maps

(Discussion)
I know this might sound weired but I reckon players should make maps with monsters and such going around. you can add a town in one corner and another in the other and invite friends to the map and try and fight your way accross. you might think that it will be unballanced because of drop rates and exp but if you couldnt controll the drop rate it would be pretty cool. and also that you can't add bosses since people would just farm unique weps and sell em.


 * Why this is a good idea
 * gives a place for you and your mates to hang round and train together
 * first GW game to be able to do it in


 * Why it may not work out
 * Would generate more exploits than a desert has sand. Easy one: trapping a hundred melee enemies on a barrier and then pounding AOE spells. Even if the loot is not transferrable to GW itself it'd be a testing grounds, and not just for benevolent purposes. Might be an option to give an editor for GW1 at some point if it gets deserted.
