I was thinking of this … have a load of pvp guilds join ‘their own’ server where the rule is mandatory and total flagged for pvp … choose a very lightly populated server get a number of volunteer guild names and a join time, so all start at the same time … maybe beg amazon to aid you by allotting one server to full pvp players only. If demand is there they can always make another one. It wont be full loot so no programming changes demanded and I cant see why they wouldnt do it.
This is Ekera right now. The few regions in yellow are from a guild that leaved the server. (Guild who only did pve for be overgeared/level and win wars)
