Remove Darius
Darius is without a doubt the easiest champ in the game to play. He provides nothing other than a decent top laner who can win his lane. After laning phase he starts to fall off and provides nothing unique. There is nothing special about his kit and he does nothing well other than win his lane. The best Darius is slightly better than an average one and the only thing that makes a bad Darius is intentional feeding. He will never get played in LCS and is basically a champ for people at low levels to play while not having to think.
I know Riot won't ever remove a champ, but if for some reason they do decide to, Darius should be at the top of the list.

So, I'd like a word with you about "easy"
