Spin to (Almost) Win Monk - Whirling Slash Thorns Martial Artist - Path of Exile 2 (PoE2)

This is a build concept I have been working on cracking for a few leagues. This is the closest I have gotten it to fully endgame viable. It comfortably clears 3 Tablet, T15 maps. It has cleared 200% Deli as well, but it starts to struggle a lot there. So I'm turning to the community for some ideas on how to scaling the damage further.

The build is using the Dreadfist Goves with Way of the Stone Fist to deal our thorns damage on critical hit. When we have a power charge we have 100% crit chance on whirling slash and thorns. We also have Barbs II which applies our Thorns to our next six attacks, so we double our thorns damage in those instances. Splash damage also creates the opportunity for additional crits and therefor additional thorns hits. Whirling slash's attack rate is ~4.5/second, so it is dealing a lot of thorns damage frequently. However, it is not quite enough to feel good with some of the harder content, but it is very close.

I'm hoping players more familiar with scaling thorns damage can help me get over the hump. Uhtred's Exodus can help me squeeze some additional damage out of Scavenged Plating. A higher attack speed spear could also work but they can get very expensive. I also have a pair of high armour, life, and runic ward boots with 3 sockets ready to add with Legacy of Briarpatch. So defensively I stand to gain ~25% additiona armour and ~500 additional HP, which I think will be enough. But offensively, it just needs to clear a little faster.

If you have any idea, please let me know. True spin to win is so close to a reality.
