As I said before I think Reaper overall is fine. They should probably either remove positionals on Reaper or make it so hitting the positionals on Reaper gives you double the Shroud gauge for caring enough. And hitting positionals in Enshroud replenishes Lemure shroud stacks to extend your burst phase. Or each positional beefs up your Communio.

Death's Design is likely to stay because of Dungeon and Raid mob fight interactions with getting a whole lot of Soul gauge build up. Soul Gauge accumulation is huge in big mob packs and in raids by tagging multiple adds across the 3 alliances.

Would love a way to make Harvest Moon more prominent. Maybe some kind of interaction with Harpe?

And I think in those rare cases there should be a way to get to 8 stacks of Plentiful Harvest without 8 people in 4 man dungeons. What would be cool IMO is if party members kept the AC buff for 20s you could keep getting stacks and could use Harvest Moon at 4 stacks and keep getting stacks until either the buff runs out or you use Plentiful Harvest.

As for SMN and MCH I feel those are rather faceroll braindead classes where if the button is ready you just press it and go ham.

The only thing Reaper was nerfed in was outgoing healing from Crest which to me it isn't a huge deal. Was amazing in dungeons during Enshroud with Bloodbath. The sustain it had would make a Warrior applaud and a Dark Knight cry.
