I like this map and I have been playing it in 1vs1 mode. However I think that map makers should start to take into consideration this new mode when they design a map.
I have noticed that this map has an issue with 1vs1 games. Since the British fleet is comprised of only 3 territories I have had many games where a player started with the 3 of them already in his possession with the initial drop.
In a 1vs1 game this basically hands the victory to who gets this lucky drop. I think the minimum territories per continent should be at least 4. I don't know if this make sense but would it be possible to add another ship (or perhaps 2) to the British fleet? It might solve the problem.
