You could easily duplicate this, dunno why I never had Unconscious there to begin with although that said (IIRC) I think I left it out simply because I thought it was too powerful.
It was made Str vs Will which I suppose is about the athleticism of leaving an opening that really isnt one... its about body position not glib tongue work.
Well, system-wise it was about STR being the prime req for fighters and thus the only allowable option for their powers to use. Its fine to color it that way, and I don't have a problem with that, but 4e still has an awkward time with these things. It doesn't handle a character with a wide variety of tactics very well in mechanical terms really.
I do think for a Bilbo Baggins version it would be Charisma Vs Will and have a higher range LOL
Well, I interpret CHA as an ability to relate with other people, so it is both related to how well they relate to you, as well as how well you understand them. So fooling someone is IMHO a CHA type of thing, classically. WILL is the corresponding defense. You could even argue for using certain skills, like Bluff, or Insight.
Actions are simplified and only one roll and one attribute... the need to attack from a position of apparent susceptibility seems a fine justification for making CaGI typically a Str vs Will.
Bilbo was wanting to move large numbers longer distances and probably included marking like effect but didnt necessarily involve the striking back.
In fact I've considered renaming skills as 'knacks' or something similar, since I think 4e's use of them is not really that close to the classic RPG concept of a skill (IE specialized knowledge and training on a specific subject).
I'm not arguing CaGI is 'wrong' as written, there's certainly room to have a few different interpretations of things.
In an adjusted 4e we could tie the distance of the draw in based on Cha ie encourage a specific secondary attribute and only deliver the damage if they end within weapon reach ... this could make them reach weapon users happy. And warlords mixing it up with fighter powers too.
