Decisions on what maps are made by the council, as a general rule of thumb its frowned upon to be asking for particular maps on servers, unless its brought up in the context of "hey this might be a cool map to play on for a Monday Madness event". With that said I still wouldn't want a second dustbowl map, in order to implement it you'd have to get rid of another map thats already being played which always leads to trouble. Secondly, you'd be further limiting the diversity of maps eGO is offering to the community, another major negative in my opinion. Besides, is waiting 15 minutes tht big a deal? Just tick off the box that says join as soon as a slot is open and go join an open game for a couple minutes.
