I thought of this a while ago but never really bothered to say anything because it was sort of an out there concept somewhat like Ivern on release but probably more difficult to make. Anyway, I always thought the idea of having a champion that is more than one character permanently was a cool idea. Like some guy who controlled 3 dogs, one for each ability, or something along those lines. Of course that would have it's own balancing and technical issues, not to mention difficulty actually playing but after watching the Sylas Dev Doodles I figured something like that wouldn't be too technically hard to make. I guess it depends on how it's designed though. It's a pretty loose concept but I always thought the concept would make for a cool jungler.
