Seeya, I got mine.

Dungeons are good for quite a few things:

-Grinding XP for the next level. and the next. and the next.

-Quests which give shiney new loot, gold, and xp.

-Shiney new loot.

-Reputation. To buy shiney new loot with.

So the question is- what do you do once you've reached your goal? Once you've leveled, or finished picking up all your quest items from the dungeon, or gotten to the reputation that you needed. Do you stick around, finish the dungeon? Or do you bail out?

Too often I've been in a dungeon, grinding along, throwing balls of pewpew into the faces of mobs, moving toward each boss and ultimately the end boss. The group is good, the opposition is dying, the loot is shiney. When suddenly! A person in the group will ding, with the telltale sound echo'd by a couple "Grats!" Usually, the group will continue to tear through the dungeon. Occasionally, the recipent of the ding will have popped smoke before the "grats!" can even be delivered. Sometimes, they'll bail out in the middle of a pull. Or two or three or full pulls. Not really a problem if it's just a DPS class. But when the tank or heals do this, a normally mundane run becomes suddenly hectic.

I can somewhat understand why- Once you gotten what you wanted, any further effort is a waste of time and energy without any benefit to you. However, it is also exceptionally rude to simply bail out of a run without any excuse or apology, especially if you're a needed class and in the middle of any pull.
