Is your feature request related to a problem? Please describe.
The trigger "Player/Unit Info > Pet > Pet Behavior" only displays the options "Assist" "Defensive" and "Passive".
"Assist" is not a thing for pets in Wotlk Classic. They have "Aggressive" instead of "Assist".

Describe the solution you'd like
"Aggressive" to be selectable in the "Pet Behavior" trigger.

Describe alternatives you've considered

Nevermind. Did a workaround fix by using separate triggers for Defensive and Passive with "Inverse pet behavior" option checked.
