No balance change should be looked at in isolation. With higher forts, less accurate tactical bombers, reduced Axis repair rate, and reduced HQBU rate, less Soviet men will be killed in the period of easy victories. That offsets corps size change, obviously without 1:1 guarantee. All patches are tested so that no drastic balance changes will occur. Smaller balance chances are possible and actually welcome, since changing meta means the game is fresh, and there is always something new to discover, new roads to victory. I know many things are unrealistic, including Opel Blitz fuel consumption or lack of horse economy, but my policy was to always allow for changes made on historical ground (one small step towards accuracy), unless they lead to drastic balance changes, even if I can't make all things to be more accurate in one go. Denniss makes data changes, and very rarely I voice dissent. Let's see what he will say.
