It seems like you see this whole discussion as a push for race and time spent on training as being set as the deciding factor in CRP?
Let us not forget that Combat roleplay is about ROLEPLAYing your characters ability and that means that you wont win every battle. Even if we are to bring race and time spent into the equation; We still role for actions that we are uncertain of the outcome, while also trying to consider the actual size, strenth and expertise to help guide the outcome of each CRP.
It should by no means be a key deciding factor but when a human attempts to overpower an Orc or pierce plate armour with a standard sword, thats when we should reference what we’ve just descussed. Rather than seeing it as the deciding factor, perhaps you should see it rather as a guideline to push for better quality in roleplaying within combat.
