Here's a few little things that aren't that far-reaching from the expansion, but I thought were more than worth sharing.
First, a rumor was going around that Iblis, Blade of the Fallen Seraph (a one-hand crit sword from Razuvious in Naxx-- pictured right) would be switched to a main hand sword in the expansion, and Neth says that even though it is currently set to main hand in the expansion beta, that's a bug (whew for all you dual sword rogues out there). But then she goes on to say something even more interesting: the reason they were messing around with the sword in the first place is because they're tweaking all kinds of weapons around the new ability of Shaman to dual wield. Very sweet, especially if you're a Shaman-type like me.
And secondly, I hadn't heard this before, but it's great gnews for gnomes: Escape Artist will be instant cast when the expansion hits. Finally!
And lastly, if you've been wondering what Shadow Word: Death or Mutilate (new Priest and Rogue talents) looks like in use, click those links and wonder no more. I think it's great that Blizzard is really going all out to make sure that the expansion is really going to play like almost a completely different game. They're streamlining all kinds of things-- even stuff that just has its own little niche in the game is getting a nice, close look.
