Ok, I will concede that AA is used primarily (and not only because there are lines which increase health and mana) for adventuring.
Another poster made an interesting suggestion - what if craft XP was used as small bonus to TS faction? Then again, I guess the same arguments could be made - it would trivialize the content of grinding writs for +150 faction and the same request could be made for Adventure writs after maxing out AA. Hmm....oh well....
dead thread I guess, leads no where positive at the moment.
