Farming by leaving zone?

[Naethyn]

This is my understanding:

1. Outdoors you can only claim one single spawn point.
2. Indoors you can claim multiple spawn points within line of sight.
3. You must already be in the zone when it spawns.
4. You must engage a spawn within 30 seconds.
5. You are not required to remain in the zone if the spawn is not up.
6. Specific camps can have alternate well known rulings.
7. If a player has more than 4 mobs aggroed you may take mobs off of them. (bard kite)
8. If a mob spawned as a result of a quest or event you have 20 minutes to engage it. (cleric epic, aow)
