Ringtones? Riot PLEASE? :O

I was just curious why Riot doesn't have ringtones on iTunes?

It's a way to make more money for the company and it would be extremely badass to have some of our favorite quotes from champions.

Like Shaco's laugh. (because I love Shaco the most.) Or DEMACIA from Garen or J4!

So many options.

I know there are plenty of places where I could download them and use certain apps to get them on my iPhone, and I know I could just get an Android phone and blah blah.

I was simply curious as to why it hasn't happened or if there are any plans in the future regarding the idea.
