What you are talking about is the OD for the sentinels but with more power and more hassle. The sentinels could have one short burst of overdrive to help them speed up and change direction quickly in midair. The outrider's OD and the raider's OD are both mostly for capping purposes. The OD adds some speed, but adds a lot of maneuverability, allowing tight corners to be made while capping the flag, especially in maps like Nivosus and Moonshine. The current OD system, while taking away health, doesn't cripple the player as opposed to how I think your system will work. If the generator blows up, for example, can you ski at all? If you can't, then the greatest purpose for OD was just taken away. One change that I would give to the current OD system is to make it easier to shut down. Push R to start it, push R again to stop it. Also, why would anybody need a drag parachute? The entire point of this game is to move quickly, not to stop. In this game, if you stop, you die. A drag parachute is, in my opinion, a lousy idea.
