I have a general question about "boosting."

1. Do you pull a couple rooms with slaves in tow, or do you pull while slaves waiting in the back and you go back to the slaves before aoe-ing? If the latter, then how do you make sure the mobs don't evade? If I use aoe, I'm afraid they may kill the mobs before the slaves are in-range for xp.

2. Do you get the quests for instances or are these waste of time as well? Some of these quests are at the end of a rather long chain. But the turn-in xp from them are incredible, especially with RAF.

3. Summoning stones. Do they work with a level 80? As in, can a level 80 use the stone? Can a level 80 be summoned to the stone?

Thanks
