My friends and I are old people now and we can't always all be ready to play at the same time. If my buddy and I are slooping and a third wants to join in, we have to either stop in the middle of what we are doing and lose all progress, or spend another 30 minutes disengaging from our current situation and turn in all of our loot to avoid wasting the time we have already spent in game.

I know that the limitation of server sessions is based on boat count, not type of boat, so I'm a little perplexed as to why this isn't possible for us to do. Sessions are "locked in" from the beginning, and it stifles the online friends flexibility I think we should have in a game like this.
