Altema has her rated at 9.5. SS tier or whatever. Here are the reason from what I can tell. 1st she’s the 2nd best healer in JP (instant cast, huge range), all her spells are instant cast and have large aoe ranges as well as being multi height and can cast down unlike other mages, she has AOE disable. Her LB is not quite quicken but it’s aoe.
Her TMR looks very fun for manual. Maybe on vinera/kitone if they can use it. It will allow them to move up to 13 spaces ( with auto quicken for an instant turn. You could assasinate someone before they even get to act, and advanced things like teleporting and evasion unit into a group with and aoe spell set to nuke everyone from a safe distance
