So here's how my first day in Wrath went:
The first thing I did was make my obligatory death knight. Not so much because I wanted to level one to 80 first thing off the bat, but I knew it was still early in the day and I wanted to see the death knight storyline before it got too crowded and before it was rendered completely irrevelent.
It turned out to be a good thing because there is one quest that's made better for having a group of people around. Look at the screenshot below.
There's a quest that involves an attack wave of death knights, and if you'll notice, most of those death knights in the picture are other players. Much, much cooler knowing that there's a whole mob of people with you.
I played my DK until the DK-specific quest material wrapped up and then parked her in Org, where she has been from the start of her play time until the end of it, the only female tauren death knight I've seen.
Then I came back on Hana and sent my druidic butt up to Northrend.
I chose Borean Tundra to start in because I understand the Taunka are there and I figured Hana would be happy to meet her distant bison relatives. I've since found that I don't like their models very much though. The males look like their faces have been pancaked in and the females are just female tauren.
The initial set of quests around Warsong Hold didn't do much for me, but once I got past that they were more fun. I understand Borean Tundra was more crowded than Howling Fjord, judging from my guildies who largely ended up going to HF to avoid the crowds, but after the immediate area around and to the west of Warsong Hold it's not so bad. It's also nice seeing Saurfang put in an unexpected appearance in what would otherwise be just a random quest chain.
The western coastline quests involving the mist? Very cool. The quests themselves aren't so unusual, but the environment in which they take place in is really what does the job. And there are nice touches to other quests where you'll even get transportation form one quest hub to the next.
Borean Tundra also had Hana's first experience with a vehicle. I'd played with them in the Death Knight starting zone, but I can safely say that nothing prepared me for this:
Moonkin on a siege tank! Yes, moonkin will not shift out to caster form when riding a vehicle! It was freaking hilarious running around the Plains of Nasam as a moonkin on a siege tank and literally mowing down Scourge. I'm sure they had no idea what hit them. Now if only I could see a druid doing this in tree form...
