I apologize that I don't have the rulebook with me, but somewhere in it (I think either under "recruit" or "activation tokens") it says that you can recruit to activation tokens.
In our game this past weekend, I abused the hell out of this - using the supremacy bonus (on one of the order cards - i think Mobilize) to "activate a second area…as long as it doesn't start another battle." So I would activate an emtpy area but not move any units to it, and then later in the year recruit to that activation token.
Now there is some debate about the ability to recruit to an activation token. Only in one section of the rule book does it mention that possibility and no where else.
Can anyone shed some light on whether or not this is officially in the rules? I believe I did my homework by searching these forums before I posted but I saw nothing on this topic. I read about a revised rulebook coming in a new version - perhaps someone has a glimpse of that?
