Can anyone explain the Evelynn rework to me?

As far as I can tell this rework is worthless. It appears they've tried to make Eve into a burst assassin except all the burst depends on an ult that has an insanely long cool down.

I'm not a great player, but I manage to go 15/2/17 most games as Eve. However, I lose almost every single game I play. How does that make any sense? She just can't out carry people like Yasuo. So how are you supposed to carry as Eve?

I do the usual build. Runic echos, lichbane, protobelt as my core. I counter build people with things like hour glass. It doesn't matter. A yasuo that goes 0/10 and has terrible farm in lane still does 100x more damage than Eve late game. It makes no fucking sense to me.

How do you carry as this character?
