Can you split North America and South America? Or at least make it so that you have the ability to play with people who actually speak your language be it Spanish or English or whatever.
EDIT: Throwing in a Riot post and a response.
You know, if we could, we'd have one server for the whole world. For the solar system, even; let those astronauts on the ISS get in on the action! Unfortunately, that's not entirely possible.
We never split to get rid of players. That idea is just ridiculous (and a little ugly, as well). We split because we have to, in order to provide everyone with an ideal experience.
However I doubt you will actually do something like this so would it be possible to perhaps give an option for whether you want to play with Spanish (and whatnot)/English players. This is a team game and for one team to not have the ability to communicate properly it could mean a frustrating loss.
I don't think having seperate language servers is something that only English players want. I have no doubt that someone who can only speak Portuguese would rather play with other people who can speak their language. At the very least it would be nice if you could make a system that puts a priority on grouping people with others who speak the same language as them.
