I was just sitting and thinking of NPCs I just don't see in the game anymore. The first that came to mind was Samantha Swifthoof. She was the Femtaur that walked the road in STV from the bridge near the rebel camp, down toward the Gurabashi Arena. Haven't seen her since the cataclysm.

Who do you miss in the game and what happened to him/her?
