I've been trying to find out about the auto turnins to no avail. It's been rumored and I'm pretty sure I witnessed it, that the NPC's at some point begin to turnin items on their own? Does this kick in at a certain point? Has anyone measured at what rates the auto turnins happen? Just curious :)

When the scepter and all the non loot quests are completed by at least 1 guild on each side ( ally + horde ) then the npcs start helping you at 5% per week. ( i think ) CJ 03:11, 7 Feb 2006 (EST)

I wonder if it is still possible to "do" the quest for the scepter, and get all the rewards, except ofcourse the legendary mount. You can still get the Broodlord's head,, but other than reputation does it serve any purpose? I havent heard anyone actually crazy enough to do so though. CJ 09:41, 8 May 2006 (EDT)
