So, interesting thread. Just in the middle of PLing another twink, he at 59 atm with 70 spent plus 29 banked or so. From what I gather after reading this thread I should simply shroud him from now on and spend a few days doing damage shield PL, since I make about 100AA per day using that tactic. In a few days I could unshroud, sitting at 500 banked AA, and then just start levelling without worrying about AAs at all for a while. Very cool, and I'm just amazed at having randomly stumbled upon this thread just before I was about to level him to 61 in order to have something to spend banked AA on.
