Darius as an Assassin

I know that during that last 2 years, there have been several discussion and thread about the problem with Darius kit. Unforgiving at close range, Unable to stick to his target, no escape, no mobility and the never ending discussion about his Ult.

This thread is about what if Darius was an assassin. Remove some of his damage from his Q and W and even armor if needed.

I would like to see Darius more on pars with Zed and the like. He comes out of the jungle build some blood stack on you before taking the kill, but wait, if he kills you and you have a team mate with low health he might go down as well. Kind of like a melee Karthus. If you and several of your teammate are very low on health, you better teleport back because if Darius is roaming around with his ult up, its the end for you guys.

I could see maybe is W becoming a tool of escape and mobility.

His Q - Decimate

(While Crippling Strike(W) is active) _ Increase damage and throw enemy back (Like Janna's Ult) much needed Escape (and utility for team fight)

His E - Apprehend

(While Crippling Strike(w) is active) _ Change ability to a dash (like Grave or Lucian) with maybe a decaying bonus of movement speed or debuff on slow.

Or maybe a bonus of movement speed while running near bleeding target. (For Much needed Stickiness) (All about that "Don't turn your back or expose your neck")

I am usually build like a glass cannon, and if I am fed, I am a serial killer on the battlefield, even without much armor I fear nearly no one. But if I get kite, Gank and zone early game, I tend to be almost of no use outside the very few occasion were I can use my Ult to finish someone but then I feel bad about KS'ing my ADC. Plus as soon as I make the slightest mistake I am done, unable to escape the slightest engage.

What do you guys think ?
