I agree with you on both Volks and Obers. I'd also like to see the raketen get a wider firing arc and shorter aim time, possibly in exchange for making it stationary while cloaked. There are too many times that it seems like they should be firing at a vehicle and they don't.
One could test making the RW work as hand held rocket AT weapons.
High mobility and response times with less penetration/damage and deflection deflection damage. More like an AT squad with longer range.
