I agree with Brahm with the note that it should be "possible" strengths and weaknesses with more information revealed as a fighter progresses.
I mean, I could come in and tell everyone my Jiu-Jitsu is awesome with having no JJ skills at all. Then, that would be revealed in the fights themselves.
I think it'll make it more fun to follow the fights to see what you can plan for based on previous experiences as opposed to just a "Guy A is the shits on the ground. Ground him." kind of thing.
