[/say #aa]

This is just an FYI throwing it out there typing /say aa hp stats does not return a result.

/say #aa - This works
/say #stats - This works
/say #hp - "Your access level is not high enough to use this command"

Specifically tested the AA. Maybe a client difference?

Paladin AA Inquisitor's Judgement is broken.

Character gets buffed correctly, but the proc spell is missing. Client gives "Invalid spell proc 21747". Looking at spell file, this appears to be true for all ranks of the AA.

Some for Rogues:
AA Envenomed Blades does the same thing. "Invalid spell proc 13753". I did not check spell file for other ranks.
AA Ligament Slice buffs the rogue with Ancient Parry VIII
AA Sleight of Hand has a missing proc spell, 16112. I did not check other ranks.
AA Dirty Fighting has missing proc spell, 23994. I did not check other ranks.

Zerker:
AA Bloodpact has missing proc spell 12706.

Paladin AA Inquisitor's Judgement is broken.

Character gets buffed correctly, but the proc spell is missing. Client gives "Invalid spell proc 21747". Looking at spell file, this appears to be true for all ranks of the AA.

Just tested this and don't see the same issue.
