I think it would be cool if there was a tiny little button next to each character in the party window. If I click on it, or maybe hover it, a little box could pop up with info about that character. Or maybe a right click on their name in the part window and hold. Or maybe just hover their name in the party window. Soandso 65 Magician 1100 AA points or Soandso 70 Cleric Journeyman 5
What about /role and /anon? Even though PUGs really don't exist anymore, having someone's AA # would be the new gearscore check needed to join the group. "LFM snake tunnels, must have 4k+ AAs."
Something you can do now: make a hotkey for "/whotarget". Then click it after targeting the person you want to know about. Or if you prefer to just type it, "/whot" is enough.
AA counts can already be checked, via the compare button in /achievement. There's no anon option for that. And we do use it as a raid qualifier.
