Since the dagger is top sneak tier any opportunist can just skip it and dump daggers entirely- saving at least a perk from sneaks tree for something else. Possibly more than perk since the top of the tree isn't a goal anymore.
agree that it kinda lets the air out of the dagger thief thing. As it stands daggers aren't optimal, looks more like an RP choice.
Makes sense.
If the numbers don't stack then daggers will STILL have great use if you took that perk. Just keep on on your person. Other perks say different weapons are better for an open fight.
