We should be able to change the language of our client. No?

Simple stance. I think we should be able to choose what language is displayed and voiced in our clients without switching servers. I'm learning Korean, and would love to have the game displayed in korean, along with hearing the announcers, so that I can learn new words, phrases, and overall feel comfortable with it while also playing league. Many players may have English be their 2nd language and it would also help them feel a lot more at home. Riot, have you ever pondered this idea? If no, why not? If yes, what was the reasoning for not doing it? Thank you for your input.
