Lee Sin's kit is hard to master, but there is no need anymore

I always see how people argue about how Lee is OP and the answer usually is that he is rly hard to master. So i thought about it, and i think that truth is somewhere in the middle. Lee WAS hard to master, and he actually is, but there is no need for using him as before, u can reach the same effect with no effort like before. I think the reason is that redicilous damage everything has right now. I tried to learn to play him, and i was surprised how easy he actually is. Not as easy as some other champs, but GP, for expample, is much harder than Lee, and actually has counterplay for every champ, with no need to pick someone special to counter him. I played Lee for like 10 games and insec people with ward bacame so easy, but you don't ned to do it if you can kill someone with RQQ under tower.
