Regarding Darius
I don't think Darius is a bad champion at all. The rework seemed somewhat great for him. But the changes that happened most recently slapped together hurt him, I don't mind the delay on his Q, but when they reduced the damage you took for standing in the inner circle to 35%, and decreased the outer hit box of his Q swing, it hit him a bit too hard. The reason I'm just saying this is because most of his match ups that he used to counter now can actually beat him. And considering their is a number of other problems he has, like his uber low base movement speed/no mobility in his kit/easy to kite, and extremely easy to gank.
Put shortly if he tries to push he risks getting ganked/getting out dueled. Or being pushed in, not snowballing, leading to him not really being much of an impact.
I'm not asking for a numbers change at all. I just think the Q hit box changes just need to be reverted.
