tbh I think all of the 8 and 24 man raids should be mandatory for MSQ progression, not only because some like Eden are actually vital to the story, but because they can also actually use the characters that show up in these raids in the story outside of cameos, AND because since crystal tower is still the only mandatory raid series, crystal tower raids STILL occupy the grand majority of raids you get in alliance roulette, even with the ilvl cheese gone
