Like I said, your opening can be explained. At the time, it was a head-scratcher because I don't think that is the direction I personally would have taken. But, I was not part of the negotiations. Only you knew what you were discussing with the other nations. That's why your opening could work given a certain set of circumstances of which I was not privy to.
The rest of your post, kind of proves my point. Yes, England probably has the best starting position. But he ultimately soloed because the other 6 nations, as a group for whatever reason, failed to come together in time to stop him.
In this variant, I think the alliance that needs to form is R/A/T (my favorite alliance acronym by the way). I thought that alliance might be forming based on the Winter '00 builds but, alas, it never came to be.
But I disagree that England would win 50 games out of 100. It would not take long before players adjusted to the strengths and weaknesses of each power and the game balanced out. Not that I'm in any rush to play enough games of this variant to provide a correct statistical analysis.
