Feedback: QuarterMaster/Suppliers/Marshals
If these guys can't do anything on our island - (meaning they're useless because they can't attack any camps on our main island), then there really is no reason for them to "park" and take up space.
Therefore, I suggest (as feedback) that they do not take up space at all. And that you should be able to directly from the Star Menu assign and remove units as necessary. They don't need to transfer around either. When they return from expeditions/missions they should retain their troops and remain accessible through the star menu.

A while back, a lot of suggestions have been made about the Quartermaster being a "Boat" when they're returned to your island. I think this is a great idea. They should just be boats harboring on the edges of our islands waiting for troops to be loaded. They obviously can't attack any camps on the main island so there is no reason for them to take up valuable land space and moving around the land mass. It just makes more sense for them to be a boat rather than a single man walking around on a horse.
