The developers take and have always taken input from the public, and fact is a lot of RS5 is based on input from players. Going through this board (and its sub boards) alone would already reveal several topics where the community is asked for their input, with the best input to be implemented in the server.
If you're going to make a topic about how the developers should listen to the public more (or even further, allow the public to decide what the gamemode should be), you'll just be wasting your time.
