A couple of days ago I dropped AO maces I think from the spider, which I'm going to feed to my 4th or 5th alt. I only camp the first bosses on either dungeon, so the spider and the firestarter orc woman. And when a page drops I stop farming and continue with other no less tedious farning routines. After been doing this on and off for at least a year, I have AO shields on all 6 relevant characters, but my crafter is still missing the staves which is the last one.
On the down side, getting that page is going to take a while. On the bright side I sold an AO shields page last week for about 60k. Been getting a few Briarheart daggers and axes too, so not too shabby. Slow? Yes. But not a total waste otherwise.
Edit:also, no. Camping a boss does not rely on other people farming the other bosses. They have a fixed respawn timer. I've spent enough hours camping them to know that there's absolutely nobody going by for long periods of time (in the wee hours) and they still spawn on their own. The best part of that is that it guarantees loot every time, while when they get a forced respawn because the others are being farmed, they will drop gold and nothing else.
The only time dungeon bosses respawn outside of their set timer is when someone who has not completed the quest for that dungeon comes into the area the boss is located; at which point it forces a respawn, but your loot timer is still ticking away meaning you will only get gold for killing it until the next respawn.
