We wanted to avoid people simply never playing a particular map. If you wish to select a specific map there is always the option of hosting a private match and giving the private match key out in the Kong chat window
excellent game, engaged developer, very frequent and good updates that correspond to what the players want, the gems don't get in the way of the game at all, and it is a fun and neat concept. This is how a strategy MMO should be done. Well done and I hope you go on to make more games like this in the future.
