User blog comment:Meat Bun Pie/Regarding Champion Concepts/@comment-8050014-20141005195538

This is a good point; however I think it's unreasonable to think that Riot would actually make a champion that's identical (or even highly similar) to a custom champion that got posted here, for a variety of reasons ranging from plagarism and crediting issues to the fact that many of the champions that get posted here are neither balanced nor actually viable in actual gameplay.

Correct me if I'm wrong, but I'm pretty sure that this wiki is neither owned nor officially maintained by Riot. I think its pretty possible that when designers run out of ideas, this wiki is one of the first places they turn to. So it is possible that some of the champions here may have contributed in small ways to existing champion designs and kits (I myself posted a champion who has a gameplay element functionally similar to Azir's Sand Soldiers!), but highly unlikely that a champion will ever be created that is actually BASED ON a custom champion.

Congrats on your first blog post, by the way, fellow Summoner!
