Having finally finished the puzzle quest, most of the moogle quests, and the MSQ... I want to second this comment. Not just the Minion and Mount guides, but the entire patch as a whole was total continuity porn, especially for those of us who've stuck it out since the Sixth Astral Era. So many random little "where are they now" moments, both stretching back to 1.xx and within ARR, so many opened windows onto the backstories of NPCs we've seen since the beginning. I'm a really happy lore fanatic right now.
