You know, you guys are taking that discussion in a very OTL-centric direction. England I can buy on the basis of history (unless we are changing the origin of the game) and Mitteleuropa from population (candidate volume), but then Judea likely has the same population advantage that Mittleuropa would have. Cincorop and Macedonia would make then obvious sources for friendlies which would bring up their averages as well.
It's a question of having to base matters on OTL to actually have something to base comparisons on, otherwise everyone will just go 'oh well in my ATL I'm a major footballing power because of [x]'. So England is a top ranking nation OTL and has gained Wales and Normandy which easily compensates for losing the Newcastle teams, Germany is a top ranking nation so a country which is basically a greater Germany is definitely going to be one. Chrobatia combines a couple of good teams with some other bits so is probably not a favourite unless we've utterly destroyed some of the other major footballing powers. Milan I would rank as a 'normal' nation but one which probably qualifies more often than not, Norway as OTL is a relatively low ranking European power, Brittany, the Baltics and Cincorop are our definite minnows.
That of course leaves Macedonia and Judea which are on the wildcard/normal borderline for me, and will be determined by who else we have as much as anything else. For Judea in particular, Israel is a decent team OTL but the rest of that area is basically non-existent for football. Now, matters are obviously changed somewhat so it's likely that the whole will be significantly greater than the sum of its parts, but we really do have to treat that a modifying condition of OTL, otherwise this entire concept will just end up falling into problems.
As I said, since it hasn't been decided if it's in Baltica or *Poland, I left it blank until it is resolved.
Personally I'd give it to Baltica.
Chrobatia claimed it first by a significant margin, and the old Grand Baltic Duchy was Estonia+Lativa. I'm happy to have it in the former, certainly more so than some of the later extensions which I'm a bit wary about.
