Need help with Mathil's Rolling Magma Deadeye build

Build: https://www.youtube.com/watch?v=FwjC3Fs0wXw

I found out too late that the Inevitability jewel was removed.


I'm halfway through Act 10 and my character is really kicking ass, rolling in the DPS! But I just found out that the Inevitability jewel is no longer in the game. How good is this build without it, and should I give up or at least significantly change it? I didn't invest into my gear, and I have a lot of Orbs of Regret, so I could respec into another, similar build. I'm not finding many fire builds out there, and not a single Rolling Magma build for 3.21. Alternatively I could just go on, but I need to be able to clear all of the endgame content for this build to be worth playing for me.
