Champion name pronunciation?

So, a lot of people pronounce champion names differently, and some champs never really have their name said in a quote or whatever, so people are left guessing, and I know it bothers a lot of people when someone pronounces a champion name differently than them, so why don't they show how to pronounce their name right next to their name when you go to see their details?

I know this isn't really helpful, but it's kinda of cool for those who hate to be corrected on the name. (Like me)
