I pretty much agree that SMN had such awful changes made to it and got new skills that didn't really make up for any of it. I'm only level 64 right now so I can't give a full opinion yet but the current changes that irked me the most was the change in Aethertrail Attunement and Aetherflow not stacking anymore, the Ruin III nerf and especially the Bane nerf.
The Aetherflow changes just made the job more punishing than it is, and I did like using Aetherflow abilities during DWT to take advantage of the magic buff. Now that's not possible.
Also I think they should make Ruin upgrade to Ruin III, have a bit more MP cost than Ruin II and increase its potency from 150 to 180 in DWT instead of reducing MP cost. Ruin IV's potency can remain 200 or increase to 230 honestly. Right now I think the Ruin spells aren't impressive even with Ruination.
It takes some getting used to but hopefully SE realises that SMN is the most punishing job to mess up on so they didn't fix the problem.
