I'm in love with this city. Just made 71 last night (yeah, I've been taking it real slow, enjoying the sights), and quickly made my way to dragonblight to get my portal. I play horde, and have always been jealous of the Alliance for having Stormwind, which I've always viewed as THE quintessential fantasy city (maybe I'm too caught up in my youth with the idea of knights and castles, etc).
So when I started walking around Dalaran, I was very happy - it's got a very similar feel, in that the buildings and walkways, etc are similar, but it also has that mage-like feel to it, which makes me feel very much like I belong. Silvermoon city could have been like this, but I think they went a bit OTT there ...
Dalaran is pure win ... and FFS, what's the deal with being agro'd by a blinking shark in the sewers ... I nearly crapped myself.
