To reiterate what everyone said, have your animas, and come prepared with the necessary consumables (cookies, reraise, food, poison pots, etc.). Make sure you are aware of which animas do what, and use them strategically.
My favorite setup is: Whm, Blu, SMNx3, War or Rng. If everyone uses their animas properly, and you make sure the players who need the mob still to 2 hour before people start throwing their terroanima, you should be just fine.
Your party seems like a successful setup though. Good luck!
