Does using Enslave Demon on Elite mobs counts as "Disrupting gameplay"
Today I discovered a cool ability in Warlock's kit called "Enslave Demon". I went to Hellfire Peninsula to play with this ability and I looked for the badass demons I can enslave. I found the Arazzius the Cruel and chose him because he looks exactly like Lord Jaraxxus. However, people started cursing me for doing this because this demon is an objective for Cruel's Intentions quest.
Is this considered disrupting gameplay? I asssume it would count as disruptive gameplay if I enslave him 24/7, but not for just an hour?
