Most of the champs you listed are extremely frustrating when they're ahead and lack any meaningful counterplay when the person playing them is decent.

before the nerfs. For Annie, as long as you don't group together in a teamfight, she can only really blow up 1-2 people at a time and has to get right in their face to do it. Azir could completely wreck teamfights with his soldiers and wall from complete safety, then turn your own turrets against you during pushes.

if you're playing a fed toplaner. Ashe can be outplayed - dodge her stun/volley, catch her out of position, punish her when her support is stunned. Good luck getting near a Kalista with her spirit watchdogs and constant jumping. Oh, and if you manage to catch her support out of position, nope, she'll just grab them and throw them at you.
? really? You're going to pretend this dude is ok? Just him simply being in the game means you can't play aggro at all. You have to let your enemy free farm. Enemy Nasus top laner and Cho mid? Too bad, you have to deal with them at 40 minutes freefarmed and fully stacked with 4k hp each because there was a Shaco. If he wasn't unpopular he would absolutely be my #1 ban since 2009. At least with Eve you can pink ward gank paths and ward her jungle - she can only move in straight lines. Shaco can come into your lane from any direction, and its impossible to watch for the smoke from every single angle. Just awful fucking champion to play against and I'm so happy he's being nerfed. His mains are also awful people in general.
