I'm not sure if anyone talked about this on here before or not, but it seems the Unshackled joined the Horde after Nazjatar. Neri Sharpfin, Vim Brineheart, Poen Gillbrack, Mak, and Friend Pronk can all be found next to the docks at Dranosh'ar Blockade, near/in the water.
I know Neri had talked about "going back to their real home" after Nazjatar, but it's possible that Orgrimmar would become home for them.
I haven't seen anything about the Ankoan after Nazjatar, however.
