This strategy uses two tanks. We killed all Moogles before King summon and had no death, lasting 15:40.
Compare to one tank strategy, second phase handling is somewhat easier, and less burden on tank / healers. Though as a trade off, the DPS requirement for first phase is higher and it is harder to "hide" someone.
The video focus on the tank perspective while shows the general strategy for whole party.
