You'd have to get in first. Doing so without getting crippled, at least, is extreemely unlikely, which means your superior physique will loose its significance as a deciding factor.

Plus, the rest of the competitors have arguably equal close range potential, each and every one wielding some manner of weapon, having varying degrees of armor (but armor nonetheless), and retaining access to elemental tricks.

It's probably not going to be fun for you - i know it wouldn't for me. It's going to be almost too tough to serve as a worthwhile learning experience, even if you are a martial arts nutjob.

Here's another perspective: an RP fight is still tough as balls and most certainly will make you think even when the characters are an even match.
