Looks to me like the Rooks are getting tired of playing defense most of the time on the large map.
The strategy of having resets by capturing bases is no longer viable with this situation, or Rooks are going to lose interest in playing the game, imo.
The whole reset parameters shoud be looked at closely, perhaps adjust the base capture concept to one which relies more heavily on strategic losses, including, but not limited to a set # of planes shot down. I like the idea of having statistical presets, beyond which a "country" wins or loses the "war."
Well, better stop now, 'cause I don't know much about computers, or how hard it might be to make a change like this, or even if anyone wants it. Just my opinion, FWIW. Sure hate to see the Rooks thinning out so much.
Big salute to the Bishop and Knight players who came over to help the Rooks.
