I also think that the mg feels a little bit too strong., but soviets have enough to counter mg spam like mortar, sniper, m3 flamer, shocks with smoke grenades.
I wrote it to say that the British are not needed, the Soviet Union can be given two more factions.
Before the release, developers say - this game will focus on the Eastern Front.
I see what you mean, but, if there comes a new faction, it should be brits than a new soviet faction. I think most of the coh community will favour brits. In addition its easier to give soviets new commander than a new faction. Thats why i don't think it makes sense to create a second sov faction.
As for streaming, back in SNF 5 qualifiers I streamed on twitch with lowest quality to the closest server and it lagged the games like crazy! Eventually I got screenshotter to work and never tried to stream again.
You have enought time to beat more challangers at the SCK Cup to buy better hardware
