How can you jump to results of the poll? I've submitted my preferences but didn't view results and now I can't.
Also regarding map choices, I think it's good idea to introduce later a weekly map rotation, where matchmaker focuses on 6 maps from approved map pool per week.
Some of rotations could be themed - like eco maps like comet catcher, gecko, needle or eye of horus, small maps, water maps, flat maps etc. Just rotations.
Maps that aren't currently in map pool, but I enjoy and would like to play from time to time are: Zed, Cold Snap, Obsidian, Tartarus and some water maps.
