Fast Track is also quite powerful as well.
Still though, I've only just really started my Rogue playthrough, so I haven't come to any conclusions yet about these skills.
My "Rogue imbalance" concern is that in the past patch, to give Way of the Rogue things to do, daggers were changed to 3 AP and no backstabbing, and Way of the Rogue 1 lowered the AP cost of daggers back to the 2 it was before, and WotRogue 2 added backstabbing to daggers. When this patch changed things around and made those bonuses no longer needed, most became Talents, including both of those ones. Both those talents seem kinda mandatory to make the daggers compete, and having two mandatory talents seems a bit much.
