Removed in Cataclysm.
I remember doing this quest chain. It was fun in an oh-dear-God-save-me-so-many-regrets-why-Blizzard-why sort of way. The quest series by all rights ought to have been marked as a bunch of group quests due to the sheer density of mobs.
But I impressed Darthalia, so I guess I have that going for me.
