DH GoD Build error with CALAMITY

[Caladon-1291]

Is Calmity Worth Running?

I’ve been testing different setups for the new GoD build (don’t want to just copy the leaderboards), and thought Dawn + Calamity w/ Marked For Death - Grim Reaper might be a good way to get more Area Damage into the build. I did some searching and from what I read there was a Calamity nerf back in 2019 that made it unusable, is this still the case, and if so can someone explain why it is no longer usable?
