Actually, there are still moveable objects, and still Grav Lifts and Mancannons and such. Switches will only become more advanced and better. Destroying Grav Lifts? Delayed Kill balls Spawning into Grav lifts. That idea is claimed by ChAoTiC. Right there, that's my idea.
Erm, why are you two arguing? Sarge just clearly proved switches are not only possible but fairly easy. Sometimes I don't understand people.
Someone's gotta have the bigger e-****. I figured Grav Lift switches would still be available. Good to be certain of it.
