I wanted to stay quiet, especially not to disrespect my good friend DadBunnyWabbit

But the thread has moved away from the map rotation question and into a discussion on "Off Hours Late War Arena Change".
The map resets, as Lusche pointed out, previously came due to unopposed bases being taken during off hours play time. The consistent decline from base captures of a year ago is pointing to a trend in players either loosing interest in the victory conditions or not feeling rewarded enough to engage in chess piece battles.
My feelings on the matter, "Old habbits die hard." The game was being channeled in one direction, air combat over airfields.
The
strat war has slipped further into the background, and defenders and attackers clump into furballs and don't produce much movement.
So, a temporary fix would be to rotate the maps. A more permanent fix would be a more dynamic victory system, that rewards small group and individual efforts toward a common chess piece goal.
