"Pretty much no one can beat Fiora in 1v1"

For non-duelists: Wow it's like if you put a duelist against a non-duelist, the duelist wins.

For duelists that are extremely old and outdated (read: basically every single one of them except Fiora and a few): Wow it's almost like ancient champions meant for past metas won't fit in the new meta.

To use analogies, would you make an archer fight a swordsman in melee range and then wonder why the swordsman won?

Or would you put a person who only has a slingshot against someone with a machine gun?

Same thing.

It's almost like if you're not good at 1v1s, you shouldn't try to 1v1 said duelist who's supposed to be amazing at them. Gee because you know, who cares that you have your own strengths such as teamfighting which the duelist won't be good at.

And if other champions can't match because they're too outdated, then update or rework them like Galio was (which by the way, was handled amazingly) so they can actually become relevant again.
