A schedule for rotation would obviously be up to HTC. But, subjectively, from this player's point of view. Any map, even my most favorite maps in the set, get old after a week. It seems reasonable to meif we can't get a reset in a week there should be a scripted reset/scroll to the next errain in the set. This would accomodate all players, flying at least once a week is almost the definition of a casual player, also most squads have weekly squadnights, after which point the map should be rotated. A week would give everyone a chance to play on it, and wouldn't give us a chance to get sick of a particular map to the point of dry heaving on sight at load-up.
