Is it me or does Yasuo seem... restricted and a little weak? Maybe small buffs?

Now I am by no means saying he's not strong, in the right comps and with a coordinated team, he can become a monster, but to me his kit seems way too restricted and he seems a bit weak.

He HAS to build crit or his damage steroid in his melee ADC kit(excluding ult bonus) is non exsistent. If he doesn't build crit he doesn't get damage.

I'm not saying that is a bad thing by any means, but this just makes me seem like he HAS to build crit every single game, and the best counter for crit rushers is thornmail as they kill themselves with their own crits.

His passive shield doesn't seem to last that long, it lasts 1 second. It was nerfed from 2 seconds, to 1.5 seconds, to currently 1 second. Wouldn't it be possible to try out 1.5 seconds again to see how it is? His shield shouldn't last 1 second and should be brought up to 1.5, he needs the survivability, especially early/mid.

And the last thing that really makes Yasuo feel incredibly weak right now and generally have health/hp per level seals is his base health. He had his base health nerfed at rank 1 by 50, while that isn't a whole lot late game, it is HUGE early, where Yasuo is his weakest.

Honestly, you don't have to bring the base health back to original values, maybe test giving him 30 back, or 40, that nerf along with the movespeed nerf(also same patch) really made Yasuo a lot weaker early, but his late game was still there in a sense.

He could use small buffs, BUT before it is decided he is buffed we need to test this stuff to know if it will make him overboard, nobody wants Yasuo FOTM again and I sure as hell don't, that was annoying as hell.

Thoughts?

Edit: What's with the downvotes? I'm asking questions and wondering what you all think, downvoting without adding to the conversation doesn't help at all. If you downvote because you hate Yasuo don't vote at all.
