Yeah, I've got 5 FF6 elites to go, and all the FF4 (8 total dungeons), from the newest stuff and they've all been incredibly easy. I basically drag Cyan through them to level up, and even with a basically useless character it's not hard. The only one that messed me up was Mobliz because apparently Poison Strike doesn't count for his weakness, so I'm running the damn thing over and over without winning. Finally read that Bio works and was annoyed (luckily it's the single fight).
Itdoeshelp that Sephiroth is 50 with Masamune, so I just limit break 9999 every boss. Also up to 69 stamina.
I still need to finish up the original content (FF4 - Baigan/Cagnazzo, FF5 - Magissa & Forza, FF6 - Magitek x3, Tunnel Armor, Vargas), which now having Cloud and Sephiroth at 50, and a few more 5* items, should be much easier. I have no clue how you have so many -aga spells. I haven't found enough Dark orbs to make shit.
