Why couldn't one stab someone in the back stealthy with two weapons? That's just a strange statement. Seems to me if someone is skilled enough they could back stab with two weapons effectively. How is it a single weapon only skill?
Just seems like an awkward maneuver. Certainly, I've never heard of such a thing. I'm not saying it couldn't be done, it just seems like a less stealthy, quick maneuver. Conceptually, it seems more of a "first strike" rather than a "backstab." If you see those two things as the same, then I'd better understand your issue, but I don't see them as the same, conceptually.
If that is the concept then one should not be able to back stab with a sword either.
Yeah, I'm not a big fan of "backstabbing" with a sword, but I can see that a little bit more easily than backstabbing with two weapons.
