"Obsidia is one of the last mature dragons that can continue the black dragonflight bloodline. She must be killed."
OK, I know WoW is a game about killing things to take their stuff, but I'm not doing this quest. A little slaughter and pillage is excusable because it's 'just a game' but seriously... this is genocide. Blizzard, I'm not sure I like you so much any more.
