When rerolling, you should aim for, probably in order:
1. 100% Eidolon
2. 1 core Hime of some element you might enjoy
3. 2 SSR Hime of the same element
Ea + Ryu-Oh fulfills condition 1. Whether or not you want to settle for that is up to you.
When it comes to Souls, you'll just about always want to get Gawain, Cass, Mordred, Dartagnan/Joan. Preferably in that order. However, if you'll settle for the Ryu-Oh account, you'll want to go Cass and then Dartagnan, since Ryu-Oh gives the debuffs of all Gawain, Mordred and Joan. Still, get those Souls AFTER Dartagnan, you'll need them for other elements.
