This all seems like a fantastic idea! I can definitely help out with stuff if you're still recruiting. I've got all 8 slots full on Balmung, but if available slots are limited, I can help out on my main. If you still have slots available, I have a couple alts I don't feel overly confident with their RP classes (Hatsukiku being a prime example; she's a CNJ ICly, but I'm anxious about tackling healing 50+).
I've got DRG maxed (i230) on Hana, as well as SMN(i223)/SCH(i180-something) (But I have very little healing experience past about lvl 40 WHM) and am working on leveling and learning all of the classes (currently everything else is lvl 35+). (Although, tanking still makes me nervous)
My character are:
Hanatsuma Maibito (my main)
Hatsukiku Maibito (my secondary main)
Swyg Klyng
C'sharra Dalkuh
Cocori Cori
Olina Blacke
Miss Cleo (yes, yes, I know, and yeah, she's going to be a healer with plans to grab AST when I get that far)
Celeste Lebeau
I'd be more than happy to help with whatever roles need filling, going at whatever pace you feel comfortable with.
