Jax and Olaf with Conqueror

So I met Jax in one game and Olaf in another game I'm going to tell you about Jax first.

Jax took the new Conqueror an could easily kill everyone from the start of the game until the end, the new Conqueror his stun and is fast attacks made it literally impossible to kill him except we fought him 5v1. Same goes for Olaf and his ult, he just needs a few auto attacks in his ult to be full life again so he just kills everyone who is in fight with him. I know Olafs ult shouldn't be changed but with the new Conqueror at least something needs to change. I really like the new Conqueror and it feels pretty balanced for most champs but some got op through this rework and I hope you look into it.
