Glorious. Now, all that's left is picking up Basch's RM3.
So! Laguna bonus battles landed yesterday. I went at Adel with this setup:
Rinoa (L80): Rising Sun/Estharian Helmet/Terra's Pendant, R4 Waterja/R4 Thundaja, Devotion
Y'shtola (L65): Wyrmfang/Balamb Garden Uniform/Rune Armlet, R5 Curaja/R2 Shellga, Dr. Mog's Teachings
Eiko (L65): Golem's Flute/Red Cap/Glow Curtain, R4 Dispel/R4 Mana's Paean, Mako Might
Quistis (L65): Ochu Tentacle/Ten-Gallon Hat/Crystal Orb, R4 Magic Breakdown/R4 Darkra, Magic Madness
Hope (L65): Valkyrie/Blitz Helm/Circlet, R4 Firaja/R4 Blizzaja, Blood of Espers
Celes Runic RW
So yeah. I was wondering how well would a mage meta team perform all other things equal and the answer is pretty danged well! Adel's RES ain't too problematic once you get past Shell and she only uses it at scripted HP unlocks that aren't even interrupts. Mana's Paean was enough to have even Quistis of the Reno-level MAG breaking 9k damage a pop and Rinoa broke the damage cap even with Angel Wing Quake. Drain counters get eaten by Runic, and for some reason she was rather fond of casting Flare too. You can also throw Reflect and Drainga on your Reflect mage if you don't want to use your RW slot on Runic (I could've safely slapped Reflect instead of Blizzaja on Hope, for instance). That was pretty painless.
