I mean no disrespect.
But I do not see people joining games for community and culture. My opinion is people play for the competition first. That is why they join. As time goes by the community becomes more important, and is what ends up retaining the players, long after they have satisfied their competitive urges. But many are going to leave, and never know the pleasures of community, if the competition is not worth bothering with.
I agree grouping by language makes sense. So can we please join the UK with Australia and North America. Let all French speaking countries have their pot, the German ones their pot, the Spanish and Italian ones their separate pots.
Most people in the world can speak one of these languages. Portugal can probably join Spain.
If the game starts growing madly maybe then you can start looking at breaking the pots into countries. But as I see it, many countries are a joke, and will remain permanently so. It is not fair on their users.
