Multiplayer to this point is simply joining someone's game and following what they do- just helping them to kill Z's... not ideal. I would love to see multiplayer where the host can toggle which people can interact with their community. When someone is able to interact with their community, they are able to build and/or tear down, receive 50% of the earned resources (from outposts, friendly enclaves, etc...) to their own community, and even choose your survivors- able to upgrade them. The hosts would understand the risks- That's why they have the ability to toggle on or off who is able to interact. This will give multiplayer the feel of working together rather than just being tethered to the host.
