Mundo's ability icons got updated
While it's nice that an old champion got some attention, I notice a lack of blood in the icon for infected cleaver. Nothing in the new artwork suggests that it would be infected, and it actually looks fairly sanitary. The icon is bright golden-yellow. This changes the gory, grim, and gruesome thematics of Mundo.
Furthermore, Masochism icon shows a flexed arm. Again where's the blood coming out of his fist? Mundo is the embodiment of violence and insanity, to the point where he gets off from causing pain to any living being, including himself (if you can call Mundo living).
