Deadmines was tied into the Westfall storyline in Cata which was basically a CSI: Miami spoof involving Edwin Van Cleef's daughter who watched a party of adventurers kill her father back in the day. As for SFK, the Silverpine quests are Horde-only so that would be more of a Forsaken-related dungeon than Worgen and it still irks a lot of players that in order to know what happens to the Worgen after they leave the starting zone you have to level a Horde alt.
