After playing Spiral Knights for more than a few months, you probably have seen the same puzzle with the switches, and the same loot room. Levels seem to be made of "parts" stitched together to create the overall level. I think it might be cool if players can make "parts" and submit them for players to test and vote on. Top voted "parts" could be reviewed by a game master or someone certified. for quality control, then implanted into the game. I don't know how possible this would be. Maybe you can think of a better system. What I am really aiming for is more variety in levels.

TL;DR People make level parts to give levels more variety.
