What can you do about it... Insta is so easy: point and shoot. That's the only reason I can find why it's so popular instead of those multi-weapons/multi-rules modes.
Sauerbraten gameplay is its strongest value. The rest of the game is pretty ugly on the graphics side, the engine is getting old, my biggest complaint is that the community does not want to move on to the next generation of the engine, be it Tesseract or Octaforge. Imho, Tesseract is by far one of the most underestimated open source projects.
