Suggestion: Add new skins with new skin animation
The game is 2 years now and still we don't have this. My suggestion is to sell custom skin packs that will change a champion's looks and skill animations.
Example, for Krisk, they should release like a "Mecha Krisk" skin. With these skin he can probably shoot lasers on its eyes. Umm I don't know, just an example.
The point is, this custom skins should look more "shinier" or skills should look more "flashy".
The pack, I suggest, together with the skin pack, put gems in it something like 1000 gems in a $40 pack
