Need some help

Question: Am I just washed now? Peaked W/Illyana in season 3, I believe I had like a 60% win rate. 72 hours on her, I’m finding it harder and harder to get kills with her. The whole shtick is to brawl to farm overshield and then dive the backline, yes?

I do that? And I just get touched in ways I don’t want to get touched. I can still 1v5/1v4 with Darkchylde, but it’s her main form that I feel I’ve lost the touch with.

SO I come bearing questions. Can someone go through what a standard brawl/dive looks like with her? I have a 56% win rate, but the finals have been tanking through every new season. I just wanna figure out what I’m doing wrong

TLDR: Lacking Final hits and need help learning why/if anybody else feels the same
