A suggestion about the alliances and such.
I'm just thinking about the future, I just don't want to have my army sit there and get slaughtered while I run around the wilderness for a week.
Any possibility of loaning your army out as mercenaries temporarily? Say you set a time frame and give another play control of your assets for that time. Or just be able to give control until you take it back?
That also might be a way for new people to join an alliance with a larger army. A new player with their 10 soldiers could give control to a larger army, while fighting with the larger army they would get a percentage of the gold taken in the battles.
It would require a lot of trust among members, but the life of a mercenary is kind of like that.
