The thing is just that this thread isn't even about champions being too strong, the OP didn't equate Kled having lots of things in his kit with Kled being overpowered. He just said he was "cancerous". What you're looking for is a champion with lots in their kit who isn't usually considered unhealthy - even if someone comes along to say they personally hate them, it's not the community's commonly held view.
Urgot is bad and has historically been bad... but that's because he's unhealthy. So your post if anything agreed with the OP - you listed someone with lots of mechanics that is considered very, very poor design.
A good example would be someone like Nami whose kit is super loaded but nobody ever complains about her even though she's usually both fairly strong and fairly popular. She has 4 ways to apply CC in her kit and can do targeted damage/heals/speed boosts from up to 1450 range away - how unfair is that?
