Yep, got my invite a few days ago. Also got an invite to the Diablo 3 beta, which is kinda late since it'll be released next month, but oh well. XD
D3 looks like fun, and I think I'll be playing a good bit when I'm not busy with WoW, but at the moment it pales in comparison with the MOP beta.
I will be trying to keep my beta posts as spoiler-free as I can... but I don't know how well that's going to work out. So, for anyone that isn't in the beta and wants to keep things a surprise, I will be tagging those posts with "MOP beta"- so you can skip them if you want to. XD
And I'm still playing the actual live game too. In fact, sis and I and a buddy have been farming MC for transmog drops (our buddy just got his last piece of druid T1 :D) and have recently added BWL to the list. We're thinking of hitting up the AQ raids, and eventually might move on to some of the BC raids (I hope I hope). Fun stuff!
So. I'm off to do more beta stuff. Til next time, Happy Hunting!
