Honestly? Yorick... Why? Splitpush god, can solo baron at 20 with 3 items (yes u have to be ahead) has a good and easy kit, is able to fight off tanks, bruisers, ranged champions, and avoid ganks (unless you are a kayn and just totally ignore the fact that i placed a wall on the floor.... WHICH IS EVERY SINGLE GAME) and in teamfights, if u get a titanic hydra u can pretty much 1 shot the adc. (Trinity force, sterak's gage, death's dance, merc treads or tabi, spirit visage or dead mans plate, titanic hydra)
