Hey,
I know a lot of people who would like to play on the PVP server but without being in a large company the potential for losing everything constantly pushes us to the PVE servers. I think it would be a great idea to have a mixed server so you get the best of both worlds. My idea is to have it so Lawless servers are just that Lawless - PVP heavy and considering the islands are heavy in resources they would be worth fighting over. the other aspect is allowing Company war to enable alliance PVP between them.
This way if a company steals your land or you want theirs you can declare war and fight for it. there is obviously some speculations like the other company has a specific timeframe to accept/refuse war or it's automatic if they dispute their claims for a set timeframe. this allows the Bounty system to be used as well.
