simply if they have some real fighting experience it will inform the wrestling and make them better wrestlers, more entertaining to watch, better movesets, more ties to reality.

whether or not its an advantage depends on the wrestler, if they are a shit wrestler then it aint gonna help. and some guys it seems to not get mentioned, like santino, hardly anyone knows of his background as judo and mma guy, even though he uses judo throws in his matches.
