First of all, I'm not being rude, I'm being HONEST.
Just look at what they did to other jobs and what DRK has, if "low effort" is not appropriate, I would say 6.0 DRK is very disappointing.
Are these changes and new things expansion worthy? No.
Did they try to make DRK better? No.
I don't want this quality of change to happen again in 7.0, so I say they did a bad job on DRK. It is true. That is the honest I can give. I cannot appreciate their efforts. I don't expect that SMN-level kind of rework, but this is too far below average. If they really play DRK, they will know salted earth had more flexibility before, they will know blood weapon needs stacks, they will know living dead is the worst invul, etc. but they just... don't know.
I wish I don't have to type all these, just give me a rating system I will rate 1 star on DRK so I don't have to be "rude"
