Yeah, I thought about that, but in my experience, most times you will have full SBB regardless. I did it this way and I was fine. Also, since it's Trial X4, you get extra BC from the turbo monsters that Gazia will spawn, making BC production easier.

Another thing is that since you have Melchio, you can still hold off from using Andaria's BB or SBB since Melchio can cleanse. Also, Andaria is an extraneous addition to the squad as Melchio cleanses/nullifies, Bestie provides BB fill rate as well as BC on hit, and Shera provides her 7 BC fill per turn.
