I think it is worth testing redesign the Blendkörper 2H Frangibl which was designed to be used vs vehicles.
The ability could become a homing AT grenade that blinds vehicles/disables weapons and damaged USF crews.
I think Obers have access to this very same nade, no? Would that mean that they would get vehicle blinding capabilities too? Also I don't like this idea due to the ever growing complexity. Takes a year to learn what all abilities do already.
