Rioters cannot even look at champion concepts in fear of copyright.

Well Riot, how about you add one of those long "Terms of Use and Conditions" when making a post on the boards that you can either accept allowing your content to be used to inspire Rioters if necessary, or decline so that Rioters cannot look at your content.

Because its kind of disheartening that Rioters can't even look at some awesome champ concepts.
