if u wanna evoid to much time with building and things, u have to organice it well
example watch the camp and make a +/- camp timer like this:
but yeah at the main time on ely are like 11 swb premades and on asmo 12
so as soon as camp turns u have like max 3min time or u get over runned from the other fraction
lets say u would put a permanent gate at like this location:
its still next to the camp, and the npc for the quest is still there where it is. this could evoide i think this 3min entry window and could be a option, yes but the pvp will still stay, it will just split up the premades abit up.
and about camp timer reduction, 10-15 is to low
the better solution for this would be at list 20-30min, so it wouldnt be totally fucked up but still fair
