From what I'm reading from the people who run the numbers, these changes might actually be a nerf to the job, not a buff or maintaining the same level of DPS.

AOE skills weren't buffed by the same 30% to keep their potencies comparable to what they were before the rework, so for dungeons monks definitely got a nerf. Additionally one of the main sources of our DPS, our auto attacks, no longer benefit from the 30% damage increase granted by greased lightning. Auto attacks made up for 20-25% of our total damage before, so hitting that with a 30% reduction is pretty huge.
