Fun little fact, Sturmpios used to have shrecks (thus they have the voice lines for them).
messed-up voice lines where their voice suddenly changes. It's quite noticeable.
I don't like the idea of Panzerschrecks on Sturms, because it would make them very similar to Panzergrenadiers. And it doesn't really suit an engineering unit.
An MP40 upgrade would be nice as there are absolutely no MP40s in the OKW. But the weapon was produced a lot. Of course, an upgradeable MP40 would have seperate stats. Such an upgrade would also be a nice nod to CoH 1 Volks.
If they were to just loose the Panzerschreck without getting anything new, then I'd see their recent price increase to 250mp as unjustified.
Lastly, if people hate a-moving Schrecks, the situation could be improved if Schrecks were made to be used more defensively. I imagine a longer initial aim time and maybe a decreased range could have such an effect. The whole mobility plus AT could be the main nuisance to many people here.
