In the hands of a skilled player, no amount of damage reduction nerf will be enough because of Cauterize. I guarantee you there will still be no end to the nerf posts unless damage reduction is removed which would turn the subclass to shit. Can't change blast radius because of PvE consequences. My solution: Swap the Cauterize and Explosive Pyre perks in the subclass skill tree. That way you can have health regen or tracking hammers but you can't have both at the same time. Buff impact on 1000 Yard Stare so it can OHK on headshot.
