Alright, decided to switch up my party and so far it seems to be helping a ton more then the last setup
Last Setup:
99 Tyro: Full Break R3 | Magic Breakdown R4 | Wall | Mako Might
99 Edge: Steal Power R5 | Phantasm R5 | Eblan Doppelganger | Dr. Mog's Teachings
99 Sephiroth: R4 Lifesiphon | Doesn't Matter | Reunion (Burst) | 30% Katana DMG+
99 Vanille: R2 Shellga | R3 Ultra Cure | Transcendent Dream | Lionheart
99 Y'shtola: R2 Protectga | R5 Curaja | Asylum | Knight's Charge
New Setup:
99 Tyro: Same as old
99 Edge: Same as old
94 (Ran out of eggs) Alphinaud: R3 Faith | R1 Curada | Burst | Eidolon's Bond
99 Vanille: Same as old
89 (Ran out of eggs) Selphie: R2 Protectga | R5 Curaja | Burst and Dreamstage | Knight's Charge
With Faith + Selphie Burst + B.M. + RW DT, Alphinaud can hit 100% magic buff and combined with Full Break and Vanille's Command 1 RES down debuff, he's hitting for 3.5k per hit with his powerchain command 1, which is 2k more then when Seph was spamming Command 1 with old setup, and it is faster DMG too, so P3 should be easier now with the new setup.
Edit: Forgot to add on top of all those buffs, Alphinaud is max RD as well, so he has +12% SMN DMG on top of it.
