Nowadays most countries have English class. What I was mostly getting from KoS is why not have it available in a lot of the other languages too. I only used Philippines as an example because I know that there is a pretty decent sized community of filipino players in Era.
To get into a bit more detail the amount of English they learn at a younger age depends on the quality of education they receive. Public school is free there but the education is not that great(A lot worse than here in the US), speaking from experience I had to enroll my step-son in the private school there so he would learn more. I didn't have much money in the philippines and survived on what i earned through our internet cafe. I used to speak perfect english but after living there my grammar is all messed up and I have an accent xD
