Hi all,
You play in character game. You role play the character but choose not to use the tools and framework.
This is same like not following the rules or dice throw results in a table top game so personally I do not see a point for role played combat in the form the OP presented.
This should have IMO went down like this
Insert RP chat, brag, taunt in the opening.
Initiate a Duel.
Based on the result of it RP out and conclude.
Like Insert character name my battered but victorious takes the bio scan sample off of my marks body. [short and lazy this could nicely played out if wanted to]
Basically you are doing a LARP performance in environment that provides a framework to live it out not just pretend the conflict and the character.
I could understand this going on in the LARP scenario but to ignore the tools given to you and basically doing a LARP from your sofa is just meehhh.
I think that I probably have totally different idea of what RP is than the OP.
