My two cents:
Complex is a terrible CTF map. One team's flag is right out in the open, and the enemy can stand on top of the building and shoot at you from a distance. You can't stand anywhere near your flag to defend it, you die before you can get to cover on 50% of your spawns, and if the enemy takes your flag, you can't chase them without getting sniped from the roof of the building. The enemy's flag, however, is closely surrounded by walls, allowing them to defend easily, and their spawns are better protected. I don't remember what the colors are, but the team whose flag is in the open is at a severe disadvantage the entire game.
Also, I would like to see an occasional 1 flag game.
