Formation

What can I change on my formation to make it stronger on Skirmish?
Current Formation:

BT / StaffM / BT
Jani / Witch / Jani
Ora / Arty / Ora

StaffM level 115 :mofo:

I use a rin and it seems to help alot. Maybe take out 1 jani. I have staff main as well but put her in 2nd row. You also do not need 2 oracles. In skirmish if you die just heal for res.

2 janis is a good thing in skrimish if they have good equipment that is. Maybe change the 2 BTs out. You'r lvl 115 you can get alot better frontliners then BT.

I have the BTs because of their AOE
