Refresh, Haste, Triumphant Roar, Magic barrier, Saline coat, Occultation, Cocoon, Regeneration, Orcish counterstance (if that floats your boat). half of those have 90 sec or less duration. /RDM is a common sub for survival/longevity too so add in barspells/barstatus/phalanx/stoneskin/icespikes.
We don't have them all up at once, but the extremely short duration hurts alot more than composured buffs do.
I don't think 1 more spell every ~10 min is gonna hurt much.

The last thing we need is:
"We looked in to adding another spell that enhances the melee capabilities of Red Mage, but felt players would not enoy having another spell to cast. There are no plans for adjustments to the spell "Temper" at this time."
Like I said, it'd be great if it was added to temper, but I certainly wouldn't complain if it was added in the form of a new haste/attack% spell. I'm simply offering an alternative means of implementation, if they felt adding haste + attack + DA to 1 spell would be too much. They could have changed Raise III to behave like Arise, but they added a new spell for it, so they can do the whole "Look new spells!!!" thing in the patch notes.
