unnecessarily fragile and complicated, dokumori shares a cd with damnation so just make a 7war cannoneer pf and have ppl swap to nin when it's opposite their turn to doku (i.e. 1st in order dokus on 4th, 2>5, 3>6, 4>7, 5>1, 6>2, 7>3). i might be off by one, i think when i did it i was 4 and doku'd for 7 though. but either way they're both 2min cds so it lines up with some leeway and worst case you can still pull fine without damnation obv (or have one person who can trade off healing duty and the healer is an 8th war/doku for even more leeway).
