while still far from the most difficult champ, Annie has a higher skillcap than most people realize. No one seems to make good use of that bear.

Maybe I'm just super awful at Kayle or something, but I can't see how she's on a list of mechanically demanding champions

First champion that comes to mind that you didn't mention is Karma. The previous poster already mentioned her, but it deserves mentioning again. As does Viktor, though I didn't think of him. I don't even play him, but I've seen some skilled players play him, and it's amazing what he can do when played well.
