In the meantime, as a FC leader trying to build submarines, I dip into Coerthas once an hour on the dot for more darksteel ore... because they DO have content that uses the old zones, it's just not necessarily battle content.

1.0 had areas of the zones that were intended for endgame (which never happened.) Unfortunately, this meant level 70 mobs blocking the way in the closed corridors of the Black Shroud when you were a level 40 trying to get to Mor Dhona the first time.
