Malphite
I don't play Malphite and I only realized this because of OFA, but Malphite's visuals seem pretty outdated. His attack seems more like a slap than the crushing blow you'd expect from a rock monster. His Q animation is lame, W is just an upgrade from a single to double-sided slap, E is decent, R is pathetic. I think he needs some changes in the splash and game.
