I'm confused. Why exactly does careful attention need to be paid to "specially restricted areas" and instanced areas for this issue? Let's say I'm doing Salvage, and I invite my noob friend in Windy so we can chat while the rest of the party does Salvage. Noob friend still can't enter Salvage, get anywhere near Salvage, or get any drops from Salvage. How is it any different than going to Windy and inviting noob friend to the party before heading off to do Salvage?
