Finally got a chance to look at the book myself to see what everyone is talking about...
Wakshaani, do you know if that chart on page 47 for the various Aspected Awakened Abilities is actually meant to be a change for Mystic Adepts? There isn't any other mention of changes to the way Mystic Adepts function anywhere else in the book (in fact there is nearly no mention of Mystic Adepts specifically in the book).
That chart seems to imply that Mystic Adepts automatically have access to Astral Perception (as it specifically calls out Physical Adepts as needing to take the Power, but doesn't use the same notation for Mystic Adepts). And it doesn't mark Mystic Adepts as having access to Enchanting, even though there is no real reason to remove that. It also doesn't make any note about how Mystic Adepts have restricted access to adept powers (they have to purchase their power points separately and don't gain more as Magic increases unlike Physical Adepts).
All-in-all, that chart seems like it should have just left off the first three lines, Full Magician, Mystic Adept, and Adept aren't "Aspected Awakened" and don't seem to be altered by what the book is talking about in relation to that chart.
Also, the preface of: "Three of these 'lost' aspects follow" is sort of lacking when one of those three is just an optional rule to allow Aspected Enchanters to essentially get a free Priority Upgrade (the effects of Priority B at the lower Priority C). They didn't even give it a new name or otherwise alter it in any way. It is literally saying "we all know about Aspected Sorcerers, Conjurers, and Enchanters, but I bet you didn't know about the Apprentices, Enchanters, and Explorers, plus the minor sparks of Aware" If you're going to make a 'more powerful' (read: available at lower priority) aspected enchanter, call it an Artificer or something and make it so that they can't use Alchemy to make spell preparations. At least then they would be in line with the Explorers, no access to immediate offensive magic, but have access to a high Magic Rating at a low priority.
