I want them to flesh out "dead-ends" for every job. In RDM's case, Enhanced Moulinet feels like a dead-end. It's good damage when you do 3-5x of them, but it feels primitive and doesn't culminate in anything (opposed to BLM who can triple flare, then Foul and SMN which can Bane+Painflare+Deathflare+Enkindle Bahamut).

Realistically, I can see them adding:
-long-cast AoE spell or a spell to pair with Scatter.
-trait that while under Embolden, White/Black Mana Consumption through "Enhanced" Weapon Skills is decreased by 50% (allowing us to do 2x melee combos+finishers back to back)
-Huge AoE oGCD damage only usable at orabove 80/80 black/white mana, but doesn't consume any black/white mana.
-Trait that makes Acceleration restores 10% of your MP.

Most importantly but also the most controversial:
-Make it so Verraise does not share a recast timer with any other spell, and then make it a 30-60 second recast. They've already shown with BLU that they can create spells that do not share a recast (Peculiar Light, Off-guard). By making Verraise limited, they still have utility but it's no longer a ridiculous crutch, nor can it ever be a gigantic MP sink as it is now where we're raising 6x+ per fight. I think it's fair as a RDM that we would still be able to raise, but there should be a limit to it. This way, SMN can raise without a recast restriction, but it's still a slow 6s cast. RDM can raise instantly, but we are limited to once in 30-60 seconds. Sounds fair to me.
