Next season (39) we will have our very first nations merger! The United Nations of Africa (not an official name yet) will be the first international league to feature teams from several different countries (if we don’t count Utopia, of course). These countries will keep their national teams and their players and draftees will still keep the nationality of their original nations, but the league will otherwise function just like any other: one top division, one cup and therefore, only two B3 contestant spots. Teams will be assigned in divisions based on their world ranking, with the top ranked teams filling the top division. In case this experiment proves successful, we will consider merging other nations with a low manager count in different international leagues.
I guess they'll merge pretty soon the Caribbean for example
Teams leaving is probably inevitable. But I think the mergers will give micro teams a more competitive environment, which in the end will make more teams stay, simply because competitive games are more fun.
