Just a thought to tide us over as more maps come on line....
Right now it seems that the maps are in the same order on every list, every arena. That means we are likely to see the same maps at the same time everywhere, or close to it.
If we could see the list shuffled, so there was a different order in each arena, it might give us more variety.
After all, variety is nice even for guys who don't have a map preference -- but it can be a wonderful relief to have an alternative for the map you "hate worse than anything"
