indeed,
one of those minor itemization gripes i’ve had and seen others mention before,
so easy +1 from me 
i had to stack all the attack speed in the world to make a 2h chaos melee using Juggernaut (Tenebris not an option for said build), and while the build was still fine, it felt more cumbersome than it had to be
and it has made other 2h bonkers so “annoying” to come up with i often just scrapped XY idea
as for conduit/chaos upheaval savagery itself, it is playable using Tenebris tho
pretty sure i even saw it posted on the forum
edit. yup [1.1.9.4] 2H Melee Chaos Savagery(Upheaval) Vindicator. SR 90/Ravager of Minds
