Fair points, Maali. There's no disputing them. I guess I just don't mind playing an invisible warrior with a dagger, but you're right that there's not much else for a Rogue to do.
There are plenty of status-effect inducing skills and abilities, but the Rogue can't afford to get them. All the magic spells require 7 INT minimum. There are no Way of the Warrior skills until WotW Rank 3, which is 6 ability points.
Unfortunately, it's looking like additional Skills, Abilities, and Talents will have to wait until after the release, and I'm not sure that they'll be changing how the abilities work (because that would almost certainly affect saved games).
