Good morning to everybody!
I write from awesome @Colombia, in South America. My country was listed as a @Buzzer Beater micro-nation too, because currently, we don't have so much managers playing the game right here.
I can say that I disagree absolutely about those options of mixing countries and so on. In my opinion, the game must continue as It is until now. It is very funny and cool in that way, and It just need more spreading, for you to get more new users.
You can make more spreading, more creative media campaigns and so on, but with decision of mixing countries you are affecting one of the strongest points of the game, which is the National Teams and the unity and empathy that it brings. It makes each country community closer and makes possible that the managers become friends with others from the same country. People will Not feel totally identified with their own culture and traditions if you make them to belong to a different kind of nation than their very own country.
Please, keep the game as It is, with NO mixing countries. If you want to improve it, there are some aspects that need it more, for example salary of the Club Clerks, like Doctors, Spokespeople and so on, which keeps always growing and It affects the development of the Clubs. But mixing countries is Not the best solution, because every Nation has their own identity no matter their size.
Greetings! Keep smiling always and playing hard @Buzzer Beater!
