It'd make sense narratively too - if a front is being taken care of quite smoothly and there some of its divers are in need for more challenges, then they can rotate, or if there's a juicy fucking reward that might be shared between factions, then the people who go elsewhere actually do so with enthusiasm.

It also allows for reviews and feedback on specific faction gameplay to cater to the people who actually play them, allowing the swedes to fine-tune them into a perfect combo of gaminess and difficulty. At the very least the 3 writers idea is pretty fucking simple to do, regardless.
