Until we see people fielding suggestions in the melee thread about how to buff Magical Red Mage at an equal level to the buffs they're talking about giving to Melee, you can throw that "equal benefit" right out the window. This thread is about Magic. Aura effects would be awesome, but are really, really not Red Mage's style. They are pretty much only single-target spells, and that is likely never going to change due to balancing issues.

I don't want to get lost in neverneverland where the penultimate obscenely overpowered Mage class of FFXI suddenly needs Aura buffs and Ultima. We're not that poorly off. Small, unique tweaks and abilities that enhance what already makes us good would be ideal.

To that end, a legit Phalanx 2 would be awesome. Self-target, with higher damage mitigation and a more 99-balanced skill/potency cap. Gravity II would be awesome, and appears to already be in the works. I'd love to see Rdms get access to Break, even if its usage is limited to mostly fodder crap. Aside from that, being able to inhibit TP in some way may be useful. I believe that's a niche thing for a few other jobs right now, so that may not be possible. It would be cool, though.

An Amnesia spell would be amazing, but anything that mattered would probably just be immune so I'm not sure there's any point in adding it at all. Maybe a spell that acts similarly to Addle, but for TP moves? Forcing the monster to use TP moves either a certain % or a certain duration less frequently. This would be extremely effective on certain monsters which have permanent regain.
