Are you interested, though? Despite the great efforts put into the zone, I feel as if it's still only going to interest players who have primarily been PVPing all along. Faction-hubs-in-Ashran aside, I'm not sure that's necessarily a problem. I can hardly fault PVPers for getting new content when every other zone on Draenor is clearly dedicated to PVE. As someone who doesn't PVP at all, I have to see more Ashran before I can say with confidence whether or not I'll play there when the game goes live, but I imagine my participating will be much like Wintergrasp and Tol Barad. That is, I'll participate a handful of times, remember why I don't PVP, and never return.
Even the faction hubs being on Ashran may not be compelling enough to take me back there on a regular basis. I didn't like the Shrines in Mists of Pandaria very much. My hearthstone remained in Stormwind for the entire expansion. I just might be in Stormwind for another one.
