I like that Riot are getting rid of one-off oddball champions.
Warwick is a science experiment instead of a random Werewolf. Good. Fizz is a Yordle now. Good.
I'm sure the initial idea was to flesh out their environments at some point, but it never happened, so those champions never had an ecosystem of champions to interact with and Riot simply couldn't do lore events (comics, cinematics, etc) for them.
The same goes for champions like Fiddlesticks, Shaco and Nocturne. Just rework them into Demons and call it a day.
I really wish I had a reason to buy skins for those champions or play them but their gameplay and lore has no depth.
