You have GOT to fix this.
Darius absolutely cannot 1v1 with ANYONE. I've been trying for a week to get this new style figured out and the more I play, the more I want to drop Darius forever. if Garen gets destroyed the same way mobility wise, both my mains would have been trashed and I'm off to Smite. Do you people not give a damn at all how actual Darius players feel?? There is no reason in the world for a level 13 champion to have less than .7 attack speed. This "item synergy" you speak of is non existent when he can't even land the hits fast enough to matter. A full QWER combo does less than a third of a bar of damage with perfect execution. Expecting to land any auto attacks what-so-ever is a joke the way he is currently set up.
I'm trying really hard to see where you want us to go with this style of play, the delay and spacing of Q, I really am. But it's NOT... WORKING. We can't beat other melee champions at our own game. Jugger-NOTs. And don't even get me started on what it's like to play a Teemo in the top lane, which is a thing. I feel like Don Corleone in the garden scene with his grand kid replaced by Jigsaw.
Please, for the love of God, fix this handicapped senior citizen version of Darius. Some attack speed, the old Q back, SOMETHING.
