All you need to know about the current balance of the game was summed up rather nicely by Aimstrong in his interview after beating Sepha for the COH2 championship:
Aimstrong: While watching the games I could see that the game seemed very close. While playing it, I never felt I was completely on the back foot. When you play the same opponent for so many matches, you realize some of his habits. Sepha made a very good attempt to handle my Soviets in G5.
I think the turning point was his attempt to checkmate me by driving the flamer half-track inside my base. With the way AT nades work, it was a very risky move but with high rewards. It was doomed to fail since I had called in a second Guards squad to replace a lost Conscript squad. I never felt the half-track stood a change against 2 Guards and AT nades.
Although I was off the field, my unit composition was intact. With the Soviet snipers, this means that I could take the map back with relative ease. All his teching options would eventually be countered by my SU-85, so it was only a question of time. Thus I don't feel it was possible for him to use his map control advantage that much.
The last part in bold is especially telling. EVENTHOUGH he had been pushed off the field (something that in the original COH meant certain death) he felt CONFIDENT that he could with 'relative ease' take the map back. Why? Because all of the tech advantage that ostheer could get from owning the ENTIRE map--even in the capable hands of Sepha--could be simply wiped out with one unit and one unit only... the SU-85.
