Separate key bindings for every champion

Hey Riot,

I have a suggestion, and I don't know if it's been already posted or not. If it was, someone pls let me know.

I think we should be able to set key bindings per each champion, as in which skills are on instant cast or not, instead of us having to remember to change them every time we play a different champion. For example, when I'd play Lux, let's say I'll put my q and my w on instant case, while E and R will be on normal cast. Then, I switch to someone else, like Zyra for example, where let's say I'll put only E on instant cast, and the rest on normal cast. (not sure if this would be the recommended way for either of these champions, I just put them out there for example's sake)

So basically I want the game to be able to remember these types of bindings for each champion. I think that would be a great addition, imo.

As for a proposal on how this could be implemented: I don't think it has to be something like a list where you have to change it for each champion in part. I think you could make that list internal, without us being able to see it, while every time we play a champion, the key bindings start with default settings, and after we set them, and play that respective champion again, those key bindings will be loaded instead of the default ones... or something like that, not sure if this makes sense.

Thanks and Regards, A usually-salty LoL player
