Kinda wish VerBlizzard and VerWater were spells to be used in an aoe rotation leading up to Enhanced Moulinet use. From the JP tooltips, enhanced scatter giving the extra Mana isn't even 100%. It's another random proc at 25%. The way it is now is pretty terrible in both output and "fun". I doubt they'll fix this but RDM's aoe rotation is very poorly thought out imo.

Also, Red Mage has good mana sustain in a single target scenario. A couple of guys mathed out its rotation (they even have a simulator up!), it goes MP neutral in single target.
