Lee Sin Is Overpowered

I was playing my final game of my promos. It was either win, or have to try again for the third time. I took my favorite champion, Yasuo, top lane, which is my favorite position with him. I went up against a lee sin, who at level one got his e. At first, i thought nothing of it. Till at level 2, he hit his q, dashes to me, then presses e, and effortlessly gets me down to half health. At the time, my teammates were getting fed in every lane. At around level three, this lee sin, without ignite, kills me, effortlessly, while i was at almost full health. As time went by, i couldn't physically farm, since, if i got too close, he would e me, and if i tried to dash his minions i would most likely get hit by his q, which is on a surprisingly low cd. at level six, while i was at about maybe a little over half health, lee dives me, ults me, and kills me within a matter of seconds, and at this time, he only has a bamis cinder and a dorans blade. Meanwhile, my teamates were still getting fed. I was trying my physical hardest to fight him, but when i did, he would chunk me and force a flash or i would die. he then starts to build ad items, like maw, and starts to dominate. He starts killing my fed teamates with ease, under turret mind you, and he alone single handedly carried the game. At end game, he was able to 1v4 with ease, even with my ult and cc. After the match, i looked up lee sins ratios, and realized: They are EXTREMELY high. His e, at level 1, does 121 damage! At level 1! also it hits in a wide AOE, so it can hit multiple people! and to remind you, it does 121 damage WITHOUT ITEMS OR RUNES OR MASTERIES INVOLVED. his ult, at level 6, does 348 damage, WITH AGAIN, NO ITEMS. I personally feel that lee sins ratios are WAY TOO HIGH, and they need some sort of nerf to them.

And honestly, i was not having any fun whatsoever playing that match. Lee sin is not a fun champ to play against. And i know, that yes he is mechanically skilled, but that e and ult aren't hard to hit at all. His e he just presses e and his ult is point and click. The two easiest moves have some of the highest ratios, Im fine with his q, that is atleast hard to hit, What made it worse was his ability to be tanky and bursty. It was not a fun match, and it makes me not want to play the game at all. Im really Salty.
