Finger's idea sounds better to me, as overall ofc.
not sure if it will make Dredd's issue dissapear, as he might meet again all those guilds hes actually trying to avoid with his idea, maybe for 2-3 rounds more or less.
as for the siege camps, again, if the maps where limited, then farming would aswell be limited (at least not expoitable), so my idea for that, would again be balancing via competetion. all big clubs on 1-2 diamond maps, depending to what each world has , then the rest within 1-3 platinum, 2-4 gold and silver-cooper, make them unlimited with reduced chance for SoH fragments as rewards..
(not that this will ever happen, but come exploit that lol)
