Can someone test a scenario 1B?

Basically take a main with a level 60 Pet into an instance with 2+ alts and let the mobs aggro on the pet, get tagged by the alts, and then let the pet kill the mobs (but not damage the mobs with the main).

I got that idea after reading the scenarios above and thinking of the differences in the open world between the mains and pets doing the killing and wondering if instances were coded similarly... Could really help on a PVP server...
