Sadly we don't get dedicated servers until after EA... I just hope whatever they do for MP it is enough to keep me entertained. Nearly 100 hours in a week in multiplayer and I'm slowly but surely losing interest. There just isn't enough to do, or enough motivation (things to grind for) to keep going forever.
Burnout is possible. Though I see the OP's point. Once again though. Early Access. So we can expect to see this feature expanded. In the mean time, try singleplayer or something else for a bit so you don't burn out on this game.
