The idea of somehow adding a translator is a little out there. I recently noticed a Greek client being introduced. I am, by no means, racist; and for you that jump to that conclusion for the complaints of your fellow League players in this thread is absurd and makes you seem like the person that shouldn't be playing. Back to the main idea; I would say the only way to "fix" this, would be to create a client that implements a certain language selection. For instance, if I am labeled as an English speaker, then I would only be playing with people who have that language box selected as well. In the queue, this would be an easy implementation. For those who are bi-lingual or multi-lingual, they may select multiple boxes. Simple fix; lets just see what they do. Honestly, I speak multiple languages. For those that don't I feel your pain. Communication is always key in any match.
