In my opinion the Requiremenrts for formable nations are, a little bit insane in my opinion.
Lets take greece for example, I think for greece should be enough to conquer Instabul, Bursa and Izmir should be enough to enable them to form byzantium.
Also, I dislike the fact that Fomable nations are nothing more than Cosmetic thing for your nation and and just give you core to provinces and nothing more.
In my opinion when you form a nation (Like Byzantium as Greece), it should give you some valuable bonuses, like extra stability, better division recovery rate and etc.
