here's the fun/terrible part of this forums
if we think about it, they cant use it because someone is gonna say "IT WAS MUH IDEA RITO PLS GIMME MONEH AND CHAMP AND FREE SKINZ"
im not talking out of my ass either, i remember back a few years ago a legal guy from Riot came and explained how if they used anything from here, this would happen and in legalese, they would be in the right. so this is why Riot's art, design team, sound and really anyone involved with content creation cannot and will not come here.
they gave us this platform for our entertainment, not for them to find ideas
current example of "HABBEDING" right here http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/7srYwVu5-the-teaser-for-the-upcoming-champion
these folks thinks that this screen cap is in correlation with this player concept here http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/8hhT41YP-champion-concept-dhama-the-force-of-balance
this is not going to happen, its not happening, and if it does, pray to whatever you have faith in you will not be taken into the flowing torrents of "The Happening"
EDIT: I ask a Red to prove me wrong and completely tear apart my argument with fact and evidence from the Legal division
