Pretty self explanatory. Have a separate research tree where the comm can research a better engine for itself and better armor. No weapons obviously... Don't wanna get stunned? Get bio diesel. Wanna make a quick getaway? Get 3 phase. etc etc... Y/N?
Why would you ever get anything else than bio diesel? I think you should be able to upgrade the CV like any other vehicle on the repair station.
If you really need to run away in the CV, it's probably GG anyways. Why let them prolong the inevitable?
Me too, but this has been discussed before. I think some combination where the commander can upgrade his CV with the latest armor/engine on the repair pad would be great.
