Riots stance versus reality

Relevant Username.

The reality is that any champ can be played anywhere, but it probably wont be optimal. Riot has hopefully never suggested otherwise.

I have learned that when Yuumi goes off to the river bush "to ward"... It's actually because her jungler has arrived and you're about to get your shit stuffed.

I mean that is true. They don't make the claim it will play viably thou. Dying to jungle camps and going 0-16-0 Is still playing.
