Have You Ever Wondered, That on NA...

There's a disproportionate amount of people that have English as their first language and know how to properly speak it. I'll give you an example.

A few days ago in a Yorick game of mine, I was facing a Jayce in lane. I had just forced him to back off after I brought up four mist walkers, then proceeded to bring him to about a quarter health. He says:

: I kill u 2 tim in arrow how u chunks me u suk

To which, as any reasonable person would, I respond with:

: Am I reading English, or does anyone know where Jayce's speech comes from?

It was already pretty obvious that he was a native English speaker, but he didn't use proper grammar, punctuation, or even care to spell out the word, "you."

So I've been wondering ever since, and now that I see it more often, I've been wondering more often. How many times have you met someone in game that was a native English speaker, but didn't know how to speak it?
