What Champs are lacking in Counter Play?

I genuinely would like to know from a variety of viewpoints how should Counter Play be implemented into the game and its champions what should counter play entail, and how effectively or not effectively it is being implemented now.

I think that counter play is an important part of the design of a game especially one like League For me I define it as a disadvantage inherent to ones design that isn't easily surpassed that another can take advantage of. Or it is weakness that another can exploit

Now thats is my general definition but it could get much more specific/specialized for league and I am sure that many of you have your own definitions as well

But whats key is why is it important

Counterplay allows someone a way to get over an obstacle if they make use of the weaknesses or disadvantage of the obstacle correctly, or well enough or often enough. Counter play can allow someone to take what would have been possibly an impossible challenge to have a chance to surpass it

counterplay can also exist in optimal and suboptimal ways (avoiding combat at all times, item? avoiding a constant area of threat, a kit that works against itself)

My curiosity is geared more towards what are good examples and bad examples of counter play for champions within league
