The 'pull' command is really nice
I can't remember atm if 'outofcombat' is obselete...
I'd have to look at the spell load and see..it could have been replaced by the 'pre-combat' behavior.
Basically, 'pre-combat' allows cast bots to 'prep' for combat.
Only Bards are currently coded to make use of this..but, if you look at the songs they use with versus without the flag, you'll see.
Full implementation would allow all bot classes to do whatever they need to do prior to combat.
(For the most part, it's just an indicator to tell bots to cast short duration combat buffs .. like wizards/druids .. that they would be constantly re-casting otherwise.)
You will need an attackable target to 'set' the flag. The flag also drops whenever combat begins or the target changes (or is dropped.)
