You can alter:
Code:
Character:KillsPerGroupLeadershipAA
Character:KillsPerRaidLeadershipAA
in the rule_values table.
If you don't have rows for those rule_names in that table, do a #rules store in game (on a GM account) and they should appear in the table.
The default in the source is 250 dark blue (or higher) kills per AA point.
Raid Leadership AA is not implemented however, only Group Leadership AA.
