So how are the new assassin updates?

I'm quite curious to see how everyone feels about the new assassins but mostly in the cases of . I kinda already have a feel for the other champs: is getting a lot of hate right now, but really from what I hear she's getting her own rework soon so this version is will just have to do, is gutted (though I'm not complaining I'm actually quite happy. I just really hate playing against Shacos), got his % missing health DoT removed so he's slightly less toxic now (slightly), finally got his slow removed and looks even more fun to play now. But now how does everyone feel about the rest? Is Leblanc still the same essentially? Does Katarina now actually require skill to play? Is Zed made a bit more fair to play against in a way?
