I have had many problems with players from other parties killing villagers in our party territory. So I'm making a suggestion that you could maybe make it so that players that are not in your party can't kill passive mobs (example: a Villager is a passive mob in that they aren't hostile) when that passive mob is in your territory. If this can't work out than maybe just make it so that players that aren't in that parties territory are only restricted to killing villagers.
I don't know if anyone else has had this problem, or if it's just me.
