This build is intended as a tool to gather up currency for other more powerful builds. Don't expect to be clearing high level maps fast. It works as a culler, for either maps (if you're fast) or bosses. I use this build mostly for solo farming Dominus. And that is where I would recommend it be used.
Things that changed in 2.0
The build is squishier, or rather, everything does more damage. I recommend using self cast enduring cry and either Cast When Damage Taken - Immortal Call, or learning and practicing the rhythm of also doing manual Immortal call for greater protection against Physical damage.
The build also does less damage, or rather, everything has more health. You may want to take the fire damage above witch at the top of the tree sooner, but I'm not sure what to drop for it. This will take testing on my part but I don't have the regret orbs to do it right now.
Overall the build was nerfed, but still functions. Culling for a group has become more appealing than solo farming.
