I'd suggest against the war or rng using salts, they're your top DDs. They're doing good damage even when not WSing. If smn brings meds for fast partial mp recovery, they wouldn't have to heal and could use a salt since they don't do much inbetween astral flow for this fight. If your ninja can't keep hate, he/she would make a good canidate for using salt, otherwise whm could do it if ninja gets hated planted on him/herself.
I tried looking for a SC and didn't find much that was real good. I saw a reverb(water) SC that is slug/sidewinder ---> raging rush. Done right that should plant hate on the ninja. The SC itself even with elemental ninjuitsu used before it shouldn't be that good; however, the warrior planting a 3000+ raging rush onto the ninja is always a good thing. By doing this, the smn won't have to backup the whm resulting in 2 astral flows and the whm being able to divine magic nuke a bit maybe.
And I can tell you stacked rushing rush @ 300 is AWSOME. My setup went as pld, smn/whm, blm, war/sam, sam/war, and me as brd/sam(spirits within, soul voice minuets, ice carol/minne III for pld). Our pld used invinicble at the start, and then our war let loose a mighty strikes, berserk, aggreser, warcry, and attack+ food stacked raging rush. Needless to say that 4000 damage WS pulled hate off the pld lol, and he then got slammed, but not before using wing and doing another raging rush. We won on our 3rd attempt I think and when we won finally, it was with time to spare.
I think between you guys you can do it. A war, a rng, a blm, and a smn that won't have to heal, you have enough damage potienal in my opinion. Your ninja is probably going to go to waste though unless you find a way that he/she can keep hate, such as the SATA idea. I had thf and ninja leveled above 60 at the time I did this, but those jobs don't bring much to the fight in my opinion. My team's setup was light on healing so I used songs that could benefit the pld defensively and the melee loved soul voice minuets.
I'm sure war/thf can do a nasty raging rush with only 100-150 tp, granted they can't do two since they would have to use the ic wing before starting. But at least the ninja would serve a good purpose for this fight and your whm-smn would be freed up to throw some astral flow/banish IIs/holy out. I'm all for ninja DDing too, but not for this style of a fight. Also your rng/sam wouldn't have to fear death so much from doing slug/side X 3(start with 300, get fast tp back from WS+barrage+med, and then ic wing for the 3rd) barrage, eagle eye shot, plus several normal shots if the war planted hate onto your ninja.
Having the mages using blink/stoneskin and your melee using blink bands is good advice, but that is easy to figure out.
