Hai der.
There should be a battle server where there is no money loss or gain and that of experience. Just like the clan training servers except obviously, these are not public. This way, if somebody buys a nice piece of equipment but is afraid t use it because of the upkeep, then they can use it freely without having to worry about it. I know this server will be riddled with tin cans, but so many people want this opportunity to use their things in a server other than duel without upkeep. No upkeep, no gain of any sort. Server would be epic. Just like old C-rpg, which will attract more players.
