On the fear of lack of shreks, I believe it can be compensated by giving the raketen more range and a wider arc to be better at controlling the field vs early vehicles.
Why isn't it buffed? It's very obvious that it should be if panzerschrecks are gone.
volks with faust improve synergy with raketen. Despite the shortened range, the raketen still have excellent survivability due to cloak and the ability to retreat. It's a very cost efficient unit at 270 mp.
note that the preview isn't 100% identical to miragefla's mod. For one thing the faust on the volks actually disable the engine instead of a temporary stun.
this is ultimately about the medical truck, of the faust+raketen is enough to fight the allied light vehicle. Try buffing the flak HT's pen if light vehicle turn out to be a problem. Instead of buffing units that are already decent, underused units should be buffed instead.
