Q u o t e: Are you serious man? the patch just came out just enjoy whats there.
Oh, don't get me wrong - I am. 1.13 totally revitalized the game for me. I'm even enjoying the improvements to the window mode; I've started playing a Barbarian again because Leap is fixed. I can actually run Diablo without having to portal back to town every thirty seconds to revive my merc.
But as Blizzard said, 1.13 isn't (supposedly) the end. Improvements can still be done.
