I feel that the USSR and Ostheer are in a decent place in 4v4 (except Soviet tier structure and call-ins but that's another story). I think once you bring OKW into the equation, it wrecks the balance apart.
OKW can quickly lockdown an important sector with the Flaktruck and create a shorter retreat point that heals at the medtruck. Now that their early game has been buffed, I see them as a pretty OP faction in 4v4. They have units that are perfect for the lategame. These units are also very strong and pretty good in the early game as well.
