This is a great map indeed, very fun to play, challenging and enjoyable.
The only constructive comment I can offer is that I don't understand why France offers 5 troops while when holding it you need to defend only 3 territories, while Germany offers also 5, when you need to defend all 6 territories. Also, the Balkans offer only 3 troops (2 less than France) but they have the same amount of territories to capture as France, while you need to defend 5 territories to hold them, 2 more than France! So shouldn't really France offer 3 troops and the Balkans 5?
I think this makes France very enticing and easy to capture and hold, and works the opposite for the Balkans. Meanwhile, Italy and the Ottoman empire also offer 3 troops, but with 3 territories to defend (while the Ottoman empire has 7 territories and Italy 5).
Don't get me wrong, this is still a fun map to play, but I wonder on why there such a grave imbalance between the bonuses offered...
You may want to recount your France.
N. france - Belgium - S. France - Corsica.
Other issues that contribute to the value is that it borders 3 bonus regions with a 4th one 1 tert away. Thats 5 terts to defend against (6 counting Bay of Biscay). And 3 of the French terts normally start as a neutral.
I do agree Balkans should be worth more (4) but other than that it's right on.
