Not really. Only against OH. Playing Cons, even with PPSH, was a generally bad choice against OKW at the time.
How so? 40 muni and it either increases dps or keeps it the same depending on range. I could agree the commander choice isn't a no-brainer, but that has way more factors
The price nerf and the heavy drop in usage after that, even in teamgames where resources are more plentiful, shows IMO that the issue was less in the performance of the weapon rather than in timings against a specific faction. Compare that to the SVT upgrade which still sees usage even after the price increase.
I mentioned the SVT upgrade earlier, it's clearly much better, and I would argue it's right on the threshold of being too good. Same goes for some of the OH doctrinal inf options I think you were alluding too
As others have recommended: i would just give it the same treatment as the 7man upgrade in regards to xp gain.
Yup got no problem with that change. Giving them 6 ppshs on the other hand...
