Been busy, so I only just now got around to doing the new multiplayer raids. Feels like they stepped up the difficulty a lot with this latest batch. I had to go through about 10 different groups before getting master for the 160. About half of the groups couldn't kill it at all because it was just a random mix of a bunch of melee dps with minimal healing support, so the aoe's kept wiping out the parties. The other groups that could kill it never brought sleep, so I kept missing mastery.
Finally I decided to fix both problems, so brought Ramza with phantasm for the sleep medal, and Arc with esuna + blink medica to help with heals / petrify. Of course, next group I get into is 4 healers, my support Ramza, a full support Tyro, and only 2 dps (Tidus with OSB and Terra with her SSB).
With 6/8 of the party being heals/support, no one died of course, and we actually managed to win it with mastery surprisingly enough. We slept the dragon, then focused down the eye. Then we started on the dragon, but as you can imagine, with only 2 dps and no offensive BSB's, everyone ran out of offensive hones when the dragon was around 50% life. The last 50% was literally everyone using the attack command, with the occasional Tidus OSB when he built enough SB from auto-attacks. Both other healers had a BSB, so they had infinite healing, which is what made it possible.
It worked, and mastery was obtained, but it wasn't exactly how I expected to master that fight.
I'm going to be focusing on level capping most of my BSB users now after that ordeal. Ashe bsb should be good for most multiplayer dps roles, especially with the free self-heal on her dps command.
