Which Champions do you think need a Rework (Visual/Animation/Sound)

This topic was originally posted on the wrong board (sorry for that Moderators!) so I will copy the original description I made, but a few comments were lost (unfortunately) Still! I hope more will pop-up.

Just to clarify, I am not speaking of the mechanics of a character/hero/champion, but rather champions you think would benefit from having an updated appearance, animations or sounds (this includes adding more dialogues/lines).

Funnily enough, when I was thinking that Warwick needs such an update lo and behold it was announced, so that's one off my list.

Corki is a champion that I feel need more lines for his voice. I do not play him extensively, but when I tried him for the first time I was surprised that he had so few lines to offer.

Mundo needs some fresh animations. He can keep his comical look, but he needs a bit more life put into him.

Leona, her I play more often, but she lacks a good taunt animation and more lines. Maybe a different dance animation as well?

Veigar, while I like the fact that he is comically hopping around, his visual appearance needs a bit of a rework. I do not know how the rest of you feel about this but his movement and animations do feel a bit awkward, due to his smaller stature. His voice is deliciously evil (and annoying) so at least I feel it should remain!

Add your own suggestions or thoughts. Consider this more of a wishlist than a serious analysis as to how different characters SHOULD be updated.
