@Teutonic I admire your commitment. The problem I see with a thunder dome of sorts is that, it was tried before on PvP2. I cannot remember the exact date but the nations all decided that Tumbado would be the place to go and get a good fight. And for a long while, it worked.
However this idea of a thunder dome to break the hug box can easily be ruined by the groups of people who use it, last time it ended due to a pure distrust of one another and that was it. Maybe I'm being pessimistic about the success of an arrangement such as this but I do have doubts. People gotta learn to overlook past transgressions, lest we all end up like the Dwarves in Warhammer with our big book of grudges
Good Luck. Hope something can work out.
