If you prefer to play on a realm with Spanish or Portuguese speakers, instead of English speakers, it suggests your English skills are limited.
If your English skills are limited, what game resources do you have access to?
What guides do you have access to?
What community do you have access to, that helps you be better at the game?
The people who care about performing well will gravitate to the language that helps them perform better.
These realms you speak of therefore contain a self-selected population of people who care about the comfort of a particular language environment, more than they care about performing well in the game.
