Castiel's got it right, and I think what you did with the 5-1 fight is great. I totally understand how the above LS' usage of the missions for their RP is cool now that RP is essentially limited to one or two groups per server, but when we go to XIV the situation would simply be too chaotic for everyone to maintain their own "canon" in regards to the game plot.
EDIT: And in regards to people coming up with crazier and crazier stories of their own when not relying on the established game canon, the best thing to do if they take it "too far" is just talk to them. I know when I was newer to RP I was always trying to be the darkest guy out there, and over the years I realized how much that puts a lot of people off and mellowed out.
