Darius
I can't see a point why darius has technical difficulties. If you are talking about darius being OP we can talk about katarina , Azir , Heimerdenger and many other over powered champions and if you have many reports from trolls saying darius is op I can get my friends to say that the other champions are also OP no point in locking darius in the mean time or nerfing him as I heard. Unlock Darius as soon as possible because the game is so boring for me as I like to play with
darius because I mastered him.
