Here's the build (so far).
Day 1 report:
My talent points were reset to zero. All my macros have been erased, and all my keyboard assignments have been done away with. Everything had to be reset. It's especially not fun running without necrosis, since I've taken the spells that are on the necrosis buttons and removed them from the action bar.
There are few (if any) addons that work with the beta. I expect that situation to get better rapidly.
So I ported to SW from Shatt, redid my talent points, relearned some spells that had gone away, re-wrote a few macros, and was finally able to start adventuring.
The first place I decided to explore is Stormwind Harbor, a new section of the city, with docks leading to Auberdeen and Vallerian Keep in the Borean Tundra. I never tried the boat to Aub, but I see that a a huge advancement. No more need to do an Algaz gauntlet run at low levels. This change makes it much easier for all Alliance races to get together an level by grouping.
The boat to the Borean Tundra is a big hassle. There is no boarding ramp, something I really hope will change before release. What you have to do to get on board the ship is a timed jump. If you hit the spacebar at the right time, you end up on the boat. If you don't, you end up in the water. I ended up in the water a lot before I got the hang of it. My wife joined up with me with her hunter at the docks. I ended up jumping her toon to the boat.
We arrived at our destination in good shape (except that the bug that releases a pet when you travel by ship has showed up). We got and completed several quests, mostly having to do with killing (or otherwise inconveniencing) undead minions of the Lich King.
