As a map designer I'd like to see the option to turn off certain territories so that a player can't place units into them.  The territories would function normally other than the player not being able to add units to it during the placement phase.  They can attack it and fortify through it however.

I have already proposed this.  I called them "barren" territories.

ahh

Yeah, they are really essential to creating a true supply-line style game.  I had to seriously bend and stretch the workings of the current system in order to achieve this type of game with Appomattox.
