I'm not sure if this is already a thing because I have never been terrorist, but if it is not I believe that after the 5 minutes of terror before you can kill civilians, there should be a time limit until the terror stops. It gets really frustrating when someone with full armor, stealth camo, an overpowered weapon and a speed buff runs around killing everybody and is almost impossible to kill. This could also be implemented as a kill limit, for example after 30 kills the terror stops.
