My realm is a terribly small realm off in the corner of nowhere. I have my character's hearthstone set to Dalaran, partially for the easy access to the Caverns of Time and partially because I like Dalaran. It's a little lonely, but quiet. There are maybe a half-dozen people there, usually.
I logged into Dalaran yesterday and was abruptly taken aback because the place was packed.
In my excitement over everything else, I'd forgotten all about the cross-realm zones that were being introduced. It turns out my quiet little corner of nowhere was now populated by tons of people from another realm altogether. And it turns out that realm is the home of a friend of mine from Twitter, a fellow blogger. For the first time ever, I got to say hello to her character and pose for screenshots and generally be a silly idiot.
I'd forgotten how it felt to be in the midst of a bustling city. I'd forgotten how it felt to have activity at all hours, and I'd forgotten how nice it was to just run into someone I knew out of nowhere. And in that moment of giddy, silly screenshot frenzy, cross-realm zones abruptly shot from something I hadn't even considered to the top of my favorites list.
So what's your favorite part of 5.0.4? Is it having all your achievements on all of your characters? Is it finally being able to ride around on all of your mounts? Is your pet collection completely amazing? Or is it the sudden discovery that in the great big World of Warcraft, you're not quite as isolated as you used to be?
