Especially in URF all you have to do is spam your Q,W,E.Sona. Hitting buttons is hard work.
Nah, the games just not perfectly balanced. Urgot is not that hard to play, he's just not very good.The one with statistically the worst win ratio. Logically speaking he would have to be hardest to master since those who are using him have a high correlation for losing with him (not good enough with him). However this may also be an indication of imbalance (experts use him only but he is just so poor that skill is not enough).
What? Zed is the hardest champion for you to master?Zed.
