I mean bonus besides having the CP. Faster respawn, health boost, damage boost. All options I heard.
Well, I think these CP will only be found in contestable area. While the CP without additional bonus will be easier accessible by a certain team, to get them closer to the after completing a certain objective. (lets say after escorting the defusal robot through a certain area, you will start spawning at the CP as long as it belongs to your team)
