This may sound weird but shouldn't Darius be more of an over time kill than a burst heavy?
His passive is lliterally him cutting open arteries and veins to make you bleed out to weaken you before he executes you, would it not make sense to make his kit less burst reliant and more reliant on doing less burst initial but if they keep fighting you for an extended time period he would deal massive amounts of damage as a form of punishment?
Think of it this way, if you were fighting somebody and they knew how to aim specifically for your veins and other blood vessels and cut them open, would you not over time be far weaker, less able to fight, and at the mercy of your opponent?
If he had a rework his bleed could have higher stacks, his bleed would slowly debuff his opponent with more stacks on them and dealing more damage, and his ultimate would be there as a way to secure a dying foe.
Thoughts?
Please no this is a toxic idea or he doesn't need this to function, boards obviously agrees his current kit is bad in a feast or famine type.
