So far I've gone for Shikari with Vaan and White Mage with Penelo. I'll probably give Shikari as Penelo second job as it'll bug me later in game if she's too soft. I'll likely give Vaan Foebreaker.

I'll probably have Basch and Ashe as tanks so maybe Knight/Bushi for one or even both of them.

I'll keep Balthier and Fran as Archer and Machinist and give them both some sort of offensive magic, maybe black and time....or red? Maybe I'll give that to Ashe instead.

Whew, so many choices but I'm already enjoying it!
