Rocket glitching was a term used in 0.3z. It is defined as ghosting a rocket shot, so that the rocketeer doesn't see the explosion himself, but it damages others. This is not possible in 0.4, since all projectiles are sync'ed server side. I did not rocket glitch or intended to do it.
Fast switching is defined as the process of:
> Shooting a heavy weapon.
> Switching to a sprint-able weapon.
> Switching to the heavy weapon.
> Shooting the heavy weapon.
This shoot and move technique when done fast enough, is called fast-switching.
I never performed steps 3 and 4 above. I shot only one rocket and then shot with ingrams, so you can't relatively measure the time between my two successive RPGs(because the 2nd shot doesn't exist). I did not fast switch with RPG or intended to do it.
