Beat Weigraf U++ without Raines RW. My team was:
Leon: LS r4, SC r3 (unused), Burst, Ace Striker
Ramza: Affliction Break r1, Mind Breakdown r3, Burst, Battleforged
Eiko: Protectga r2, Curaja r5, Burst, Knight's Charge
Tyro: Multibreak r2, Exhausting Polka r3, Wall, DMT
Basch: Gaia Cross r3, Retaliate r5, Apocalypse Shield, Power of Darkness
RW: Shout
The fight was pretty simple. After setting up buffs and debuffs, i focused the Knight down to get rid of his debuff attacks, then the Chocobo to get rid of his aoe heals, then finally started focusing Weigraf down. The damage was still kind of scary (2k+) through Wall/Multibreak/Polka/Protectga, but once I got Ramza's burst up it became a joke and even more so once Apoc. Shield was up as well.
Leon's damage was stellar, after Shout, cmd 2 bargain, and Eiko crit buff, his second and further casts of his burst were doing nearly 80k (9999 on crit, 7500 non-crit, and most hits were crits). Cmd2 was also like 8300 per non-crit, 9999 on crit. After Apoc. Shield was up he was basically always hitting 9999s.
When Weigraf got low things got a little hairy when he started getting Stop on 2 people at a time despite Affliction Break (2nd cast might've worn off by then though, need to hone it to r2) and the Stops last awhile despite Mind Breakdown (i know this was still up, didn't run out of uses).
Eiko cmd1 blink helped prevent more people from getting Stopped though.
