I burned lesson in RSS when I was 80 and it was a hotzone. Usually got 6 AAs during that time. As I leveled and they took the XP bonus away, I didn't go back to solo there. I did take my bard there to level and while there I checked her AA XP with me. She was getting 10% a kill. Which is very good because they are easy, fast kills. So I figured I would burn lesson one day to see what I would get solo at 85/1200+. I was surprised to find out that I still got 6AAs for my lesson burn.
