I have done the Alexander and Sky Pirates raids already, but I don’t know if there’s anything else I can unlock later.

Alexander was kind of a chore, because the first 8 sections or so, were all just one or two terrible fights each, then back to a cutscene that almost takes longer than the fights. It did pick up in the final sections though, along with the story, so at least it ended on a high note.

The Sky Pirate stuff was decent, although I couldn’t stand the story bits. At least here each raid longer, with multiple, real boss fights.
