I got my Nec in a Nec group (pet group) the other day... went to MTG and found this two-story building. We would, while standing outside, Con this npc (forget his name) on the second floor and send our pets up to fight him. When one of our pets died we would just cast anouther and so on... till he was dead. This was good xp too. But, after an hour it became boring. EXCEPT! When something would go wrong and that npc came down stairs after us. Then, it became interesting at the price of our deaths. I dunno... I still like regular groups.
