Darius Gameplay Idea

I just had a random thought that could make Darius have more counter play and allow him to have more power in his kit. This may be a terrible idea, but I'm posting it here in hopes that a Riot employee reads this and gives it at least a minute of consideration before discarding it and being like 'Nah, wouldn't work' or something along those lines. I really like his legendary skin and his lore and all that he stands for blah blah blah, but I feel he could be more fun to play.

What if Darius' E could be charged, and the longer he charges it he gets more benefits? The only benefit I was thinking of, was making the grab range longer. I, myself could see this as being a beneficial change to making Darius less of a no-brainer champion. I got this brainstorm of an idea when I thought of Sion's Q, and as we all know..many Sions are over-zealous with their Q's and miss those things. >.> Darius could be allowed to move around while pulling, i'unno, just brainstorming here. I want some Darius changes, I want him to be more rewarding, I want him to be relevant in the game, and I know that won't happen unless there is more ways to play against him besides poke him down, stay out of his range, or do more damage in duels than he does to you. Anybody else have thoughts on how Darius could be made to be more fun of a champion to play against, and feel more useful to his team later on in the game than what he currently is right now?
