Suggestion to give both PvE and PvP players something they can do together.
Allow players to take wagons out to gather resources - allowing up to 5000 weight worth of resources and then bring them back to town. The resources can then get divided up between the party of PvPers that helped defend the wagon. Also the resources can boost the amount of free resources available to the faction that owns the territory ie honey, ore, wood etc
– PvP –
Defending Team
You would have a team of gatherers and a team of defenders. The gatherers have increased gathering speed and gathering yield and the defenders hopefully have decent PvP gear to defend the gatherers and wagon 
Attacking Team
For attackers they can attack the wagon causing resources to drop. They too need a cart to be able to take any resources that drop so it’s not just a free for all. They gotta work for those resources as well.
– PvE –
NPC enemies spawn around the wagon requiring the PvPers to also help defend it while gatherers are doign their thing. Enemies could also spawn around the gatherers to make it that bit more challenging. NPC enemies will attack player attackers as well.
