I got a dupe Locke dagger, Garland axe, and Aeris staff so she is definitely going to replace Vanille in my A team. I think I am pretty set.
Vaan BSB
Locke BSB
Ramza BSB, shout, tailwind
Tyro SG
Aeris BSB
RW is usually whatever does the most damage with BSB commands after I buff.
I dont think Garland is worth fitting in there or if there is a better comp hiding with my Paine, Basch, Greg, or Snow supers.
