If you must have more of a fighter though, Darius, Jax, and Lee Sin are all awesome. Olaf is good but he negatively snowballs HARD, so you have to have a good game on him and not lose first blue. Shyvana is another fantastic choice and probably who I would recommend the most. Very tanky with her ult and just deals punishing amounts of damage. Fastest safe clear as well (Mundo is faster but not as safe).
