You can RP about what you want to, almost anything is fair game. But, if you want to win, you should always keep it about the match in some way. You can go off to something else but it should relate back to the match or opponent. Here in XWF, moreso than some feds, they are very keen on addressing opponents and replying somehow based on your own creativity if they "trashed" you in their own RPs. Developing is good, who is the character, from where, why are they how they are, ect. Just never forget a match is a competition. Some guys RP and don't care about winning and just write to write, which is cool, others are all about winning the match. Depends on your aspirations...
