Don't know if it is the squish or what, probably is the squish.
As a 575 Destro lock I'm pumping out 100-200k dps in BoT. In current content Mythic Raids I'm only doing about 20k dps.
Most of my spells are doing about the same amount of damage that they were before 6.02 went live. I'm able to one shot most of the mobs due to their health being way lower than what it was before (once again, thank you stat squish).
Next hotfix will probably correct this issue. So if you want stupid easy purple + embersilk farming I'd get on this soon!
In 10 resets, without a treasure finding potion, I was able to collect around 600 embersilk cloth, around 300g, 5 epics and a bunch of trash that I haven't sold yet, so I'm guessing about another 150g from that.
