My Thoughts on Champs Commonly Accused of Being OP

We all know these champs, fizz, darius, yasuo, zed, etc. Oftentimes I feel that people just call these champions OP because they personally struggle against them, which of course would not bring in a nerf. Every champ counters someone's playstyle, and every champ has been called overpowered because of it, and that is not an accurate measurement of their power.

However, fighting the champs that are very commonly considered OP, even when I know their weaknesses, can be incredibly frustrating. For example, I know that Darius is slow, everyone knows that, and kiting him is quite easy, but I don't like not being able to ever slip up at any point ever while kiting Darius, which is oftentimes how good you have to be if he's fed. I know that Darius is perfectly balanced, if not underpowered in high ranks, but for people like me who are the incarnation of Bronze 12 Darius is simply a better choice than most if not all other top laners if you want to win.

I don't think these champs should be flat out nerfed or majorly reworked, but minor reworks to make them less frustrating and more interesting, like the Warwick rework would be nice. I'm sure that some people at Riot has already realized this and are working on it, but I feel that I should say it anyway.

EDIT: Looking back at my post it looked like I was implying that none of the champs are OP, I do not think that the balance in this game is perfect, just better than what many people are accusing it of being.
