True but ppshs have been buffed since then. And they were a no brainier after that buff cause they still had that 40 muni price tag for a few patches before being increased
Not really. Only against OH. Playing Cons, even with PPSH, was a generally bad choice against OKW at the time.
OH was basically playing mostly Mobile Def Puma and they didn't have any of the benefits they currently have nowadays. Either the doctrinal options or the non doctrinal improvements to the core roster.
The price tag meant that you could fully arm your whole Cons with them, pushing for a better mid game in tandem with the T70.
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.
The problem with the PPSH upgrade is 2 IMO:
-How many commanders are there with PPSH which might lead to problems in balance. (For ex: it's far easier to adjust the power from SVTs when it's on a single commander).
-It competes with SVT (early) and 7man upgrade (late).
As others have recommended: i would just give it the same treatment as the 7man upgrade in regards to xp gain.
