Dying is the easy part

So I am going to talk about Yasuo. I recently played my first 3 games with him after practicing some rounds vs bots and I have to say that he is the most fun champion to play who I know, even farming is entertaining. Now the thing is that I won all those games with really outstanding scores and the last one with a 11/0/5 and I did not tryhard and neither was I countering anyone. At a certain point those games even felt like the ones vs bots so how am I performing so good with this champion, I never practised him and it wasn't the matchmaking either, I didn't use team builder (because mid is always full) and my team had pretty standard scores at the end. So my question is, is this champion perfect for the current meta or is it perfect for the league I'm in (Silver III) or is he even op? I mean the q and e cooldowns are super short and his passive increases gold-efficency extremely, but I don't see many people complaining about him.
