It does help and yes I see the problem.
It does take a little out of the original, as it was always important to try and keep a foothold in each reason as it could be difficult/costly to gain one later in the game. This change makes it easier for humans too
It always made it a great tactic to try and remove an enemy's presence in your home zone.
But of course I would have been unaware what the ai was doing, not good!
I would think that this being flagged to false in multi player human games would be a good idea.
Sorry if all this has been discussed a lot before.
