Ya I was a Darius main too and the worst part about it, by the time its "Late Game" the other team has full items and you dont scale better at all, not compared to a sion, who atleast gets HP stacks with his shield. I even got fed with Darius and still cant do damage. The least you can do is make the wind up more rewarding, like if you charge it up, it gives you heal or a stack even at the handle, because hes W cd is so long its not even worth the slow, and his passive may sound "OP" but there arnt that many opportunities to even get your ult off even with buff. Hes ult is garbage unless you have 5 stacks which is rare, because they always havae more speed then you since your melee. The only buff from that patch was hes "E" which applied a slow. Finally his attack speed is none existent, you litterally cant even get stacks period and you struggle in lane. I even tried running a full attack speed runes page with 3 quint's damage and it does nothing. It would force you to build attack speed early which forfeits the whole concept of going tanky. This Darius update is kind of like the Talon one, no one plays or are going to play them anymore.
-BUG FIX-
I was in game with a Braum and I had auto attacked him more then 5 times and it never proc'd my passive. I died and he even mentioned it in all chat that it was weird that my passive (rage) didnt proc. 1 more thing, I was in lane and as I was about to "W" a minion the tower killed it before my "W" auto went through and I got stuck for like 2 seconds I couldnt move.

13:30-13:38 hes "W" makes you get stuck.
