Downloaded the client, downloaded a gazillion patches, manually entered EU URLs in order to successfully copy Goldpaw to the Beta without constantly being redirected to the US logon pages which I have no available games on, and finally managed to get in!
Of course my name was taken, or forbidden or whatnot, so I was forced to rename my beloved druid before I could get in. So I am Wonderpaw of the Alliance on the EU PvE Beta Realm. I can't even remember the name of it.
Learned my new talents, got forced to unlearn Jewelcrafting to be able to learn new skills... visited the crushed Stormwind Park and relearned Bear Form from a butt ugly Female Worgen Druid just north of the Dwarven District in Stormwind, and sat down to make my macros.
So far, so good!
I'm looking forward to many pleasant experiences in the Beta. I'll level up, check out the new instances, and when Blizzard decides to allow third party addons, I'll update my (soon to be finished and also) beloved UI to be Cataclysm-ready!
Screenshots and stuff to be expected in a not too distant future!
