Darius' E is broken and needs to be fixed (major bug).
Go to 2:15 in the video. That happens CONSTANTLY when playing Darius. Riot either needs to reduce the range of the animation or actually fix it so people get hooked appropriately. I remember playing Darius before the rework and I hardly ever missed a hook. Now his hook is extremely unreliable and it makes me not want to play him, even though he is fine besides this one major issue.
