Don't hold your breath on SMG recoil being reduced. I think it's higher than real life standards on purpose, although how MUCH higher may depend on the user.
In the mod, the PP* series of weapons were highly accurate to the point where people complained about PPSh snipers. (not REALLY snipers, but they complained that it felt like you could easily kill at long range)
In fact, the PPSh had good range (as most people here know, I expect), but most RO infantry maps are NOT long-range. I'd say the longest range engagements we have in stock RO for infantry are maybe 400m at the outside, and that's on maps like Odessa when firing down the alley from the tower. Even that may be shorter than 400m.
So, for the most part, you're finding out what most armies in WWII found out: full-size rifles are disadvantaged in modern combat. An SMG or assault rifle is just as good if not better.
