I have not been lucky enough to get into beta, and I haven’t had time to play on the PTR. Regrettably, that means I don’t have a lot of first-hand insight about the impending changes in patch 4.0 or Cataclysm.
I’d advise all rogues to go read Chase Christian’s article on WoW Insider. He’s got some good commentary on the attack rotations that we’ll be trying to manage once the patch drops.
