that nook is no good for me (Prot Warrior)
i dont like the mobs being that close to the rest of the party, especially the casters.
I stay by the front door, have casters/ranged up against the door while melee stand up front and pick mobs up as they run in. Being up front like that allows me to see what mobs are breaking off to go after the casters. At that point its a simple charge/intercept or even a taunt to pick them back up.
one person, a hunter, said "that seems like a lot of running around" and it is... but when i've got 3 abilities that will move me from mob A to mob B in no time at all, it just makes more sense that way.
