I don't think he is overpowered, his ult is just very annoying. Especially since I'm adc. I don't ban him because as I said I don't think he is op but he is extremely frustrating. It's not too hard to counter him, avoid his Q, don't let him get behind you for his kick in a teamfight or gank, but... when you are facing a decent lee, he sometimes outplays you.
Anyways no idea what I want with this, just a rant.
