Id like to make the following suggestion.
Return to winning the war for rotating to the next map. Take 25% of the MA maps, make that the maps for week 1. Take the second 25% as the maps for week 2, and so on.
Why? There are more MA maps now. Contriversial (a nice way of saying unpopular) maps can now can dominate most of a tour. A favorite map may not even be seen during an entire tour.
If there are only (what?) 3? maps in the line up for 1 week, I think each map would have a fair showing during the tour. The past problem of pig-piling to get to a certian map would be aleviated, because only a quater of the maps would be availible at 1 time.
