Think about it. How long haven't we had proper new capital cities in an expansion?
Stormshield and Warspear are downright terrible. If it weren't for the portal in my garrison, I would never go there. Hell, I wish my garrison just had a portal to Stormwind / Orgrimmar instead. It's the most boring "capital" city I've seen so far, with the same boring architecture used everywhere else, not worthy of being called a capital city. But what baffles me the most, is that it's actually inferior to Shrine because it has less portals. Which is why I still have my HS set to Shrine.
Anyway, last expansion we had Shrine. It wasn't ugly, and the place made me feel "zen", but to say it was a real capital city, no. The fact that the Horde / Alliance just had mirrored versions of the same city also wasn't very original. Faction balance is cool and all, but come on. Still much, much better than Stormshield / Warspear tho.
In Cataclysm, we didn't get any new capital cities because all the portals to all the new zones were available from Stormwind / Orgrimmar. Which was fine, it was nice to be able to hang there again without wasting your time. But still, new capital cities are always nice.
That's right, the last real new capital city we had in a new expansion, was in WotLk: Dalaran. And even though back then I could only move around the city by pointing the camera at the ground (and even then I still had like 5 fps), it was, and still is one of the most beautiful cities in this game. It wasn't just some shithole with portals and the bare essentials, no, you could actually explore it. There was the whole underground sewers, the toy shop, the higher learning achievement, the fountain where you could fish up those awesome coins, etc. It was awesome.
Anyway, with the next expansion slowly coming closer, I'm really hoping we get a new capital city again. And to be honest, I would really prefer if it was one city shared by the Horde and the Alliance, because with MoP and WoD, we've seen that Blizzard is just too fucking lazy to design a new capital city for each faction. So I'd rather have one completely new and awesome capital city then just two mirrored ones again.
What about you? Do you think we'll get capital cities at all, and do you want one for each faction or would you prefer if they share one again?
