[ANSWERED]Pulling Mobs

Hey,
is pulling mobs to shattrath or other locations allowed?

Sometimes i pull mobs to citys and many players tell me its not allowed, is it true?

one mob (Pit Commander from the dark portal) dont attack other players, if they dont attack him. And all npcs (like guards) ignore him, so he cant get triggered by guards, and guards cant get triggered by pit commander. They completely ignore it. Is it still not allowed?

Sorry if my english sucks. Im from germany ;)

Greetings, Dudula

Nothing wrong with this, it is allowed.
