Wow, I am going to have to re-read those rules. I must have missed something the first time, because it seemed to me that it was just defining a Touch Attack a little more strictly than the core rulebook.I see the clarification that took place in Run & Gun now. But I also don't see that the clarification states anything about Touch-Only attacks being the only option.
Weapons such as the shock glove or baton can inflict damage during a touch-only attack. These attacks don’t benefit from net hits from the attack to increase Damage Value. Using the weapon to cause damage with a touch-only attack makes it the only attack action the character can make during that Action Phase.
I take this to mean that if you're using a Shock Glove or Stun Baton, and you do a Touch-Only Attack then you get the benefits and drawbacks of a Touch-Only Attack. If you use the weapon normally, then it uses the appropriate skill, but you don't get the benefits (or drawbacks) of the Touch-Only Attack.
After all, none of the text in Run & Gun seems to supercede this:
Attacks with shock gloves use the Unarmed Combat skill.
All it does is clarify what happens when a user uses the Touch-Only Attack Complex Action.
