Riot please do a real NERF to yasuo

I know that balance is a complicated part of every game, Leaving that point clear, i'm not able to understand what is your logic with a champion like yasuo, i knoe that he is a carry he need's a lot of damage BUT he also need to be vulnerable. Let me be explain these, so i can be more specific and clear.

Yasuo is a champion that has every single quality to be in every sinlge position and he would not suffer. Why ? because his abilities let him do an ridiculous amount of damage an d also protect him and very easy to use.

Number one Passive: I dont have any issue with a shield that can recharge with movement, in fact that's cool, but double the chance of a critical strike is not that cool, i know that that strike's do less damage, but the 10% of a 2300 hit is.... insignificant. I know that i'm not a super experienced person like your game designers but just think for a minute, with 2 items and a decent farm i' having 100% critical chance in at 17 minutes 12 or less if i'm feed. That's so unbalance and i'm not hiving the oportunity to the other player to recover from that.

Number two Q: Okay this is one of the most complicated part for me to explain or understand, the tornado mechanic is good but it has a cooldown really low and also can do a critical strike, it doesnt matter if is a normal Q or a tornado, that can thing can crit, is to damage for an ability that only suppost to raise your enemy, not destroy him.

Number three E: Okay, you NERF these ability the past patch, but analize more the situation of every player, no one use the E to do damage, the yasou player just use the E to escape or catch the other player. In fact if you'er running for him and there s a minion row behind you, he catch you and he destroy's you with an E, Q combo.

Number four R: I usually dont have any problem when i use this ability (when i play with him) but here is the thing, you are giving him armor penetration with every critical strike that he have, so if a have and all my basic attack's will penetrate the armor, and again, i just need 2 ITEMS to do these.

So let's think if i'm having a really bad game like 0/13/4 with only these 2 items , i'm able to do an 1 vs 3 with no problem, i just throw my tornado use my R and instantly destroy one of them, if they star running i just need to use my E (remember that i have my armor penetration for a couple of seconds) so 2 or 4 hit's and he's dead. I f for some reason the other player scapes, well good for me beacuse i got 2 kill having 13 death's. I'm not trying to be rude with you but if that's your definition of balance, i think that you might be a little lost.

Thank's for reading, have a nice day or night.
