Adding to my prior post, i think we could make it so players belonging to two warring factions must choose a side the moment the war begins, and go with that side until the war is over. That way sides are well defined. It's more realist.
Or we leave it so a player can be on both sides. It tends to be funnier as numbers can be balanced as seen fit, but less realist.
The truth is, i don't know which one is the better, as I'm spending little time in game... I've just begun to play again recently.
Edit:
Well, yes.
I just wrote some general ideas that were floating around my mind. If you all want me to help expanding them, we could come out with something that allows us to keep things ordered and fun at the same time..
