SHD/BRD/SHM AA recommendations

Hi all! Really enjoying the server and community. I have started a second character that combines my 3 favorite classes (probably not meta). To give some context, I mostly played EQ from Day 1 and stopped shorty after Luclin release (when AAs were introduced I think). I am not very knowledgable about AAs. Just needed some recommendations for each class on some key AAs to pick up. So far I have Critical Affliction and Singing Mastery. CA and CS look good, after that I have no clue.
