Can we give Zed more rewards for doing well in a game?

I always feel like when I do well with Zed, I never really get rewarded for it. Like the moment I get out of laning phase I don't seem to have much impact on the game, other than split pushing or getting a pick off on someone. I know Zed's not a Hyper Carry, but he should be at least in some way be able to carry a game when fed without having to make super ungodly plays, to have an impact.

Like whenever I do well with my main Yasuo, like go 8 and 3 in lane. I just destroy everyone like I should, for doing extremely well and being rewarded for doing well, while the other team being punished for letting me get out of hand so easily and so quickly.

With Zed its just kinda ehh, he'll probably kill our Adc but thats about it. We'll just destory the rest of the team because Zed's irrelevant when he doesn't have his ult up. Or at least somewhat during a team fight, since your cool downs are to long to be able to use again in a fight.

It may just be me playing with Zed but I've played him over 300 times (In normals and Ranked). During my time playing this game. And not many of those times do I feel like I have a real impact even when I'm fed.

I don't recommend just out right buffing him, but maybe make him scale a bit better when he has items? (More damage with bonus AD)
