Well, I’m sure there are players here that would do the same to me. Actually, I am not sure if there are balance issues, as I haven’t put as much effort into the allies as I need to. I see serious concerns, but it is too early to be sure. I think, as long as everyone is fine playing global, alpha +2 or Out of box rules should be fine if your other players have not “figured” out an optimum strategy. I am not sure what I would recommend for balance issues. There are some great players here that have play-tested alpha +2 and see it as balanced.
I’ll let you know how this UK plan works for allies, when I get time to test it in detail. A fix may be as simple as having the UK start the round. Remember, Germany does not need to take London to shut down their effectiveness.
