This was also posted in the EQOffline section and I just remembered it.
Code:
Aggro:SmartAggroList TRUE Mob uses hate list check to attack targets.
The above statement where is says TRUE should be changed to FALSE if you are using bots and want them to hold their own aggro.
For example, if you are playing a caster class and have a Warrior bot that can't hold aggro even though it's taunting, you want to change it to FALSE so it can. This way, the bots generate their own hate list and mobs can target them as if they were players, accordingly.
