Balance Alpha 3:
Give British Fighters over England the ability to defend at 5 or less. No new units on the board, no increased attacking strength. If the fighters leave England (or are on carriers, or scrambled over fleets, even if scrambled from England!) they don’t defend at 5, they defend at 4. This only effects BRITISH FIGHTERS if they are ON ENGLAND when attacked.
We’ve done this a few times, it’s enough that Germany’s Sea Lion goes from 98% odds to 72% odds and inflicts a lot more casualties as well, meaning Germany has less chance to push the Russians back out after taking down England (they can still do it, just takes another round usually, and if you don’t think that’s a lot, imagine the increased Russian cash for another round!)
