I have no idea who put this together, nor do I have any clue how accurate the statistics are, but I found this posted on a Facebook page. Maybe some of you are skilled in fact-checking, if you care to do so. I thought that this was pretty amusing, whether it's accurate or not! (I apologize for how ridiculously large this is, but imageshack's thumbnail didn't work because of how ridiculously large it is)
Edit: Supposedly it's posted by Riot themselves, so color me embarrassed - I don't check the LoL news pages!
