Kled is overtuned
Before I begin, this isn't a post out of rage or anything. I like Kled, he's a ton of fun to play and has some interesting counterplay, so I don't think he's unhealthy per se. However, I think he lacks weaknesses. Kled usually stomps lane due to his high health pool, extremely high damage Q, and W streoid. That's fine - there are other champions who do that. But mostly they compensate that by having a weakosh lategame due to one of the following:
Lack of mobility (Darius)
Poor teamfighting (Camille)
Bad scaling (Pantheon)
Kled has none of these things. He has great mobility with his E and Ult, and even hard CC with his Q, so the first doesn't apply. He's not the best teamfighter, but he has one of the best engages in the game - I'd say he's probably around average for top laners. And his scaling is pretty good, with extreme natural tankiness, one of the best steroids in the game (W) and high AD ratios (180 AD + 375 on Q, 60 + (6% + 5% AD) on W, 240 + 120 AD if you it both on E, and max 18+ 12% AD % damage on ult.
