The amount of loading screens in this game is kind of absurd.

I also don't understand dungeons since they are not large and only have 4-8 people in them.

Cutter's Cry, Halatali, the Praetorium, Haukke Manor (Hard) and Pharos Sirius are the only dungeons that aren't one whole map. That's 5 out of 19, which is still really good.

Raids should definitely get a pass with this, though. The Binding Coil is obviously broken up because the different turns have such vastly different presentations and mechanics to them. Crystal Tower will probably be similar, and it's okay that even the first floor is broken up into two parts (Acheron's arena and everything else), because the place is so HUGE and incredibly detailed and animated.
