I'm just going to copy and paste what I posted in the thread Lyth mentioned, with some changes

I'd like to see the nerf to arcane crest not totally rolled back but maybe take the potency closer to what it used to be. Despite my constant use of it during savage, it never really felt like it was all that impactful and my healers never specifically requested me to hold it for any mechanics, which I used to do with Mantra on Monk (which also feels way more impactful).

Other than that, Reaper feels pretty damn good. It was frustrating at the start of the expac seeing people dogpile Reaper saying it was OP and now it's the lowest damaging of the melee jobs, whilst some other melee jobs have been buffed way too much. I think a small buff to Reapers rdps would be welcome as I feel that it doesn't bring a whole lot to the table compared to the other melee jobs at this point.
