Just came back from WoD, who's still here?

I just got back from a 2-year break by the end of WoD, and my guild (ConcussioN) appears to be more dead than the slain spirit of an undead death knight’s ashes in the nether, and no one I remember appears to be active or even on this server any more. Is there any horde from WoD who still plays? And does anyone know exactly what happened with ConcussioN?
