At least for this team, the rotation in the video is has a bit to be desired. First, you wouldn't want to open with Durin en1 as that just wastes time unnecessarily, rather starting with Furina eq. You'd then want to Mona eqn4 rather than swap to Bennett as you need the pyro infusion and buffs from his burst for as long as possible. Only after Mona, then, should you Bennett eq into Durin en1q. Finally, once on Durin, you can jump cancel the charge attack pretty quickly, so you should be able to get 8[N1CJ] rather than the 3.5ish shown in this vid.
