I noticed that the daily quest "Among the Champions", part of the Argent Tournament, in Icecrown can be completed while in a raid group.
Are there any other quests that share this property?
EDIT: I noticed on the quest page on Wowhead, someone has pointed out that this quest may be bugged because it can be completed in a raid group.
There are multiple quests that can be completed during raids and most of them will also require you to have a raid to complete them if attempted at the appropriated level.
What is common for them is that they will most likely be marked at Raid or PvP and they will usually be part of a chain that revolves around a Raid instance or battleground.
