Well she CAN provide team support with movement skills like guidance, flier formation, flier guidance. You can also add some drive skills and tactic skills for mixed teams. By the end of the day, B!Ninian is more support/saboteur than offense and should be played as such with that 140 BST
you can salvage her with a blade tome since most of her power is built off of buffs instead of attack stat. You will need fury A slot and spd +3 seal as well though. It works as a solid offensive unit if you get the flier buffs on her. Otherwise she should stick to ally buffs and dancing.
You should transform her into magic tank.
Weapon: Blárserpent/Blárowl (or default weapon)
Special:Glacies
A: Res+3/Distance Defense
B: Guard (or her default Chill attack)
C: Attack ploy/Res Ploy/Buff Skill
Seal: Distance Defense/Res ploy
