Ashran, Warlords of Draenor's world PVP zone, has been hyped as one of the most exciting locations in the expansion. While the zone only opened up for play on the beta last night, it's been clear throughout development that many lessons from the game's past have been taken to heart in its creation. The devs have cited pulling not only from prior PVP areas such as Halaa and Wintergrasp, but also the Timeless Isle, which contained a potpourri of activities across the spectrum of gameplay styles.
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.
