If you really want to do something matt could you please disable the usage of radio commands in the dm. Its really fucking annoying to hear enemy spotted, and gogogo and affirmative and roger that etc etc, every fucking 10 seconds!! People just want to have a quiet dm where nobody talks(literaly nobody really does) and shoot people, without the radio commands every 10 seconds by immature retards! The majority of players dont use the radio commands, so taking it away wouldn't really effect them IMO, and personally the server is greatly enjoyable when nobody is talking at all(including me), and i'd say just to basically to make that a better experience, make it so that people don't gotta hear annoying radio commands every 10 seconds on occasion.
Also, i doubt ping limiting will do anything to the popular maps 1 as its just unplayed, though oddly more stable than the popular maps 2.
