Now in World of Warcraft, loss is a pretty apparent them as well. The loss suffered by nearly every sentient race to the scourge, the fall of the High Elves, the fall of the Broken, it seems like every PC race on WoW has experienced some loss or seen some great hero fall. In addition, sometimes there's the smaller losses as well. Like, say, giving up Archeus for a weapon with an inferior backstory and proc.
So what losses in World of Warcraft have left a mark on you? Is there a certain story of loss in the lore that especially resonates with you, or do you still mourn the loss of a certain item or NPC as you've leveled up, or even some NPC or Quest that's been removed?
