Okay, there's a LOT of misunderstandings and misinformation floating around, so let me try to clarify what I can.
Warlords of Draenor's story is about the people of Azeroth (namely, the Alliance and the Horde) venturing into an unknown world and building up a force strong enough to take out an enemy stronger than anything they've encountered before, on that enemy's own turf. While there are certainly some alliances to be made along the way, and those are definitely major parts of the story, the core theme is about you and your faction fighting for survival.
So, as development continued, we came to the realization that it just doesn't make sense for the Horde and Alliance to spend so much energy and resources building up a stronghold on Draenor, only to base their efforts out of someone else's city. We're not helping the Draenei or Frostwolves fight off the Iron Horde – they're helping us. The Alliance and Horde both have major bases of operation on Draenor. That should be where they're working from.
That, along with the continued development of Garrisons into the overall quest and story flow of the expansion, led us to the decision to develop the Horde and Alliance bases on Ashran into the major faction hubs instead of Bladespire and Karabor. Promoting the world PvP area on Ashran is a nice perk, but it wasn't a factor in making that decision.
That said, the Temple of Karabor and Bladespire Fortress are still there. We haven't removed them or anything like that. You won't be able to use your bank or check your auctions there, but they're still fully built home cities for the Karabor Draenei and Frostwolf Orcs, respectively. You'll still be able to explore them in their full glory.
As to the Alliance and Horde staging areas on Ashran, allow me to lay out a few key facts to hopefully allay some concerns:
- They're located on Ashran as a geographical location on the map, but they're not part of the Ashran world PvP zone. They won't be subjected to the realm coalescing we're using to keep Ashran's PvP area populated, and they won't flag you for PvP on non-PvP realms.
- We've also made some major improvements to the way PvP flagging works on non-PvP realms that removes "accidental flagging" from mistargeted abilities or ground effects. Unless you manually flag yourself by typing /pvp, you will simply not be able to attack enemy players, or heal friendly players who have flagged themselves.
- They're populated with guards, and the only land-based entrance is directly through the Ashran world PvP zone (including a major fortress). It's certainly possible for someone from another faction to attack it, but it's not any easier to do so than it is to attack the enemy faction's shrine in the Vale of Eternal Blossoms.
- There will be a fast travel option between the staging areas and your Garrison. You can pop over there quickly, conduct your business, and leave again if you like.
This isn't a question of whether or not Bladespire and Karabor are cities. They are. It's just a question of whether the portals to Orgrimmar or Stormwind are there or somewhere else. You'll still be able to explore them, they'll still be fully populated, and they're still going to be every bit as beautiful as they would have been with a Transmog NPC. We're looking forward to them ourselves!
