Patch 3.3's notes are pretty sparse so far, and the rogue-centric bits are really no exception. Rogues only have three little bullet points, two of which apply strictly to the leveling game. The first is that rogues will have Dual Wield right at level 1, which only makes sense. It's quite possibly the most iconic part of the class. Waiting until level 10 to get your hands on it always felt a little off. The first ten levels is hardly indicative of the sort of combat you'll be getting into as that particular class.
The second change seems to aim for that same purpose: Making the first ten levels as a rogue feel more rogue-like.
Stealth: This ability no longer has multiple ranks. While active, the single rank of this ability (available at level 1) allows rogues to move at 70% movement speed.Stealth is a lot less fun when it's as slow as molasses, isn't it?
