Nekoko, allow me to express my simpathy as someone who experienced the exact same situation, along with a friend of mine whom I was leveling with.


Both Castrum and Preatorium suffer of the same situation as many have already stated.
Best options as you might now know are look for people in a similar need as you through PF, or either of the 2 you already realized by what you wrote on your original post:
1) watch cutscenes but skip on all fights.
2) do all the fights but skip cutscenes.

For the first I would recoment the (1) but for the 2nd you might want to do the (2).

The dungeon is fairly easy, to a level where even missing half a party wouldnt suppose a threat for its completion (unless both healers are missing). As such in converse means one as an individual lacks any use to the party aside from filling a spot to get in.

Just announce you are a new player that wants to watch cutscenes and if the jerking jumps up, right click your chatbox and hide it. Then you will see the cutscenes unfold like a movie.
