If we want to complete the quests we need to do it as groups. In a raid we would not get experience or the credit I guess, for killing mobs needed to complete quests.
We would get experience for killing mobs, just not the things we need for the quests.
My suggestion was and still is, that at least for Deadmines, and then afterwards the Stockades, we go through as groups, not in a raid. They feel confining to me even in a group of 4 people (and 5 is the max for groups). If we want to go as a raid someplace, my thoughts are that we wait until we get to Black Fathom Depths, or we could run as a raid from Auberdine to the Wailing Caverns, and split into groups there (though I think that might be open enough to run through as a raid group).
For those that don't know, Wailing Caverns is one of the first instances for the horde, all the way over in the Barrens.
As always I welcome all thoughts, ideas, and criticisms, (even if it doesn't seem like I listen to them, hehe).
