Idea requirments: Destruct-able PVP arena that is reset twice a month (once every 2 weeks) Adventure mode. Result: players bring their tools to gain a tactical advantage as in adventure mode you can only break blocks with the appropriate tools. this results in more loot. less pots and more strategy in pvp than strafing.
Personally I think this idea is not very faction based and I dont think it will be that popular as most people prefer to pvp in the big areans, but good luck anyhow
