Did VD run sam geo brd whm rollbot cor mule
You have to attack from the front to do damage so yagrush is very nice with the conal petrify but not needed. You can have GEO WHM BRD each pick a person to be on stona/erase duty for.
I believe we used HM March Min Mad for songs, fury precision for bubbles, and chaos sam for rolls. We probably overcompensated a bit on the acc from our accidentally Q'd VD instead of D when scienceing with yoran+3box+2box and didn't have enough acc in our buffs. Could probably drop the mad for another min.
Alex does jack for damage, I was usually in full DD as RUN once my shields were up but swapped to defensive after each Divine Judgement while we recovered.
Priority after full dispel/mp0 was ballads+evokers up on whm/geo then rolls/songs back on the DDs. Divine Judgement seems to be 30' so if you're a rollbot cor, you can aim for chaining XIs and then hide in a corner to minimize downtime on rolls after the full dispel. Or you can be a real cor instead of mule and help do damage.
Triple Tenebrae because Alex does almost entirely light damage but a Flabra or two might be a consideration because of the petrify spam. Also triple Tenebrae gets your MP back so you can rebuff yourself.
No enfeebles/offensive bubbles because Gospel.
It's not hard per se just slow.
