I see polls for Quarry (of all maps!) and suggestions for Forgotten etc. but if there is any map I would want back it's Blade Run. Not going to go into all the reasons I like it but for those who argue against it because it can be a rabbiter's paradise - the same can be said of Forgotten, Quarry, Mirage... Blade Run is a great map. It's almost like a large Frostbyte, which, IMO, should be the template for all maps.
