Riven and Yasuo

That would be a boring predictable movie.

Would be a failure as their lore didn't turn out great

Riven and Yasuo are some of league's less interesting champions, maybe make a movie about the shadow isles, piltover, zaun, noxus, demacia, all the parts of the lore that aren't already written and about two of league's worst champs

But both riven&yas are pretty boring overall since they are too generic...
