Wich cataclysm on the horizon, my guild has basically stopped raiding.
I got shadowmourne just a few weeks ago and still have some of the five vanity items left to turn in.

I noticed the other day that the NPCs for turning in each of the five quests is not around until you kill LK so my question is:

Can you:

1. kill LK on 10man to "unlock" the NPC for turning in?
2. If you kill LK (so the npcs are unlocked) can you save the raid ID to turn in the another quest the week after, that is are the quests bound to the ID or the week?
3. Maybe there is even a way to turn in the quest outside of icc?
