I think Fiora and Jax will be undefeated no matter which duo they face. Depending on the situation, don’t forget that Jax can use AP items after the latest updates to the champion.
In my previous post, Jax and Fiora were defended the most when it came to who was the strongest duelist in the game. Then I guess this is the strongest duo, right?

Taric and a bruiser probably beats 2 bruisers
