Speaking in 2v2 terms: How much of an advantage is the variety in the soviet army dictate their wins? As opposed to one part of their army being OP.
Possible SOV starts could be:
- Maxims, Mortar, Zis barrage, Flame Engrs.
- Con molotov blobs with Flame Engrs.
- Penal blobs with Flame Engrs.
- Penals with Flame Engrs in half track.
- Penals with snipers.
That is a lot of stuff to try and counter. As opposed to say USF or OKW: - Rifle blobs. Axis is on the backfoot right from the start until they have enough engagements to guess what is coming next. Brits have a similar start: With varieties of Rifles, MGs, or UCs.
Unlike 1v1 and 3v3, in a 2v2 and 4v4 the first few engagments are critical because the points taken will need to be fought for later. In 1v1 and 3v3 the armies will be more mobile since the maps are larger generically, thus, you may be able to simply cap them later or move to another area of the map.
Id say its a very big advantage to be able to have many different possible openings. The Soviets before typically had 1 or 2 strats that were significantly better than everything else and that could be exploited since you can expect what could be coming out. Now the opponent has to prepare for a multitude of possible viable starts that can be played which is much harder to deal with. Similarly, these different opening are better based on the faction you might be facing so Sovs are good against OKW and OST for its multitude of different openings.
For example comparing USF and SOV opening. USF has to start 3 rifles and maybe a mortar every game. This works better against OST due to OSTs weaker early game but its really bad into OKW who does the same thing but is stronger early. The thing is there isn't really anything else you can do as the faction so you get the OKW shits on USF statement.
Soviets on the other hand can go scout car + sniper + penals into OKW which does well into that faction. While this opening is still viable against OST a lot of times Cons into support weapons is better since the mortar and at gun can dislodge mg42s and Cons do better into Grens than they do into Volks. Also AT guns and a longer range snare on cons better counters OSTs fast 222 or HT play. So Soviets don't really have a big weakness into either faction.
Compare that to USF who sucks into OKW or UKF who sucks into OST, Soviets just make more sense due to their flexibility into axis matchups.
