Who's most OP
If you think there's a more OP champ post in the comments. (Edit: Forgot to add some options like "Other", "Lee Sin" and "Zed)

(Tanky + hard CC + perma-slow)
Why does everyone try to pick "OP" champions when you barely know why they're op
Gotta get experience bois
hit me with them downvotes
I can actually understand most of those but... Olaf?
Life steal. Too much.
How is Olaf OP?
I think he's annoying but I tried to add as many options that I could think of.

Nope. Not feeling it. You're all squishy and stuff with that build

Honestly he wasn't even a thing I thought of until you said
Kat since your ult does 1k damage to 3 people on opposing team. She also has a reset and if she kills 3 people she gets her ult back up again. She's a mid laners worst Nightmare.

Heimer is any laners worst nightmare.
At the moment: According to Champion.gg: ADC: Jinx Support: Blitzcrank Mid: Heimerdonger Top: Galio Jungle: Nunu
According to Lolking: ADC: Jinx Support: Blitzcrank Mid: Heimerdonger Jungle: Sejuani Top: Sion
I would say
ADC
Support
Mid
Top
Jungle 
Depends on what you consider OP, and other aspects of each champion.
For example, calling an adc OP because of their damage makes me wonder at times. There's plenty of other factors to consider, such as utility, mobility, and synergy with team comps. Ashe, for example, has decent base stats and high utility, but no AD steroid beyond a short range W spell. Jinx has incredibly high AD damage, but the lowest base AS and her Q requires multiple autos to amp it up, and her utility is relatively easy to avoid compared to other adc's.
Like Riven, for example. Falls off relatively early if you don't feed her and eventually put her behind with a good, solid gank. Problem with melee attack damage carries is if they don't get fed, they don't have the range and kiting advantage that adcs do.
Just a few examples, but I don't consider any champions truly OP as long as they have some form of weakness and counterplay (seriously, one knockup stops Katarina's ult. Save one cc during a teamfight, don't blow it all at once in the beginning. This is basic.).
