I actually go Jerome -> Uzume -> CfR3 -> Zola and that takes care of early rush. Prince and Iris after that, followed by Garania for the later swarms (her skill wrecks those swarms like nobody's business). Minerva gets dropped on the bottom right slot to kill the dragon mage on the right (even with the random spawns during that time, with skill active she mows them down quick and gets back on him). Zola gets replaced by Camilla. Once just the elder is left, Garania and Minerva are out, Sybilla is in and once elder gets to melee range of her, I drop Nanaly in top right and she out-ranges the elder and can pop skill to help burn him down without getting hit in return.
Got 7 Gadoras already, doubt I'll need more if all I'm doing is AW Echidna and Anya with him (Echidna is unlikely, but who knows?). I know Despara and Adele both have IA4 but I have both their skills maxed with Rainbows... who else would use him for SU fodder?
