Thanks for the information.

I've got another question... Can something like that exist?

Sequence:
Warlock Pet 1 attack,, - case, target NOT in target of Warlock Pet 2 or 3
Warlock Pet 2 ,attack, - case, target NOT in target of Warlock Pet 1 or 3
Warlock Pet 3 ,,attack - case target NOT attacked by Warlock Pet 2 or 1

I'm planning on getting 2 Shadow Priests and 3 Warlocks in my team.
