Sadly, if they change it to solo, it would actually take some aspects out of the game lore - as the story is actually not just you invading, it is an "Adventurer unit" that is doing the raid into Castrum and Prae. As for the people running it and trying to make you skip CS's, as others have said, ignore them, and if you're vote kicked, report it.

Other options include:
- Make a Party Finder to ask for help, specify in the info, "Story driven, no cutscene skipping" and that you want to participate in the fights.
- Ask LS or FC to go with you.
- Watch the CS's and then do the fights instead your next run.
