I know many online players like to tweak their settings so the game is mainly about aim. This is fun for a while but it would be great to see more varied gameplay depth from RTCW. I would like to see a feature in RTCW:ET where some maps could be set at night or very early morning. Players would not be able to bypass this setting on that particular map so everyone is on a level playing field where tactics, stealth and aim come into play 
There is nothing more exhilarating than creeping up on the enemy and using stealth tactics with a skilled aim. Watching gunfire in the dark in Wolfenstein looks really cool. Obviously you could limit the number of maps that have this feature but I think this would add more depth to the overall rtcw gaming experience in my opinion.
If you look at most wars they are usually early in the morning or night :).
