Adding in my two gil that the MP regen is definitely either too low, spell cost too high, or Lucid Dreaming's potency is too low.
I've read elsewhere that the MP regen is still the same percentage, so while it's theoretically not that, the massive reduction in MP has of course caused it to feel that way.
Spell cost went down by 10-20% from what I can see, but they cut our MP pool by far more than that, and while we can technically get about a 25% increase on MP regen of Lucid Dreaming if we keep it on strict cooldown, it definitely doesn't make up for the drastic cut the magic classes had to their MP pools. Sure, Verraise is now "only" 2400 MP, but that's now essentially a quarter of our MP pool.
On top of that, if we die, even popping a Lucid Dreaming doesn't really do enough to keep us casting at full tilt, because we burn MP faster than it can generate. You have to hope for down time to get some MP back, or stand around being idle and hope that the healer can keep you topped off in your weakness so as not to die from the next roomwide.
I think some simple MP cost reduction would go a long way, since touching Lucid Dreaming would affect way more than just RDM.
Outside of that, things do feel like they're dying a bit slow, but that's always the case with lower gear levels, and it really just seems like they're never really going to gives us a DPS bump of any sort because of our "potential" utility, even if that's been disemboweled with the MP changes.
