Has too much happening in both kits, even by their own, and have so much commands to issue via buttons, right-click and active innates.

This is not DotA (2), LoL cannot support nor is prepared (yet) for that much, to not say that making to nearly independent yet controllable champions means perma 6 vs 5, which isn't healthy.
