So, what are your thoughts on this? If someone was really that good of a puncher, kicker or grappler, they dont need any other ranges of fighting?
My thoughts are that you don't need to be skilled in all ranges of fighting, to be an effective fighter, or to be able to effectively defend yourself (these are not the same thing, by the way).
You do need to be very good at applying your skills against people who might try to attack you using different methods and different ranges.
Just a friendly observation, but I think you've been having the same discussion over and over for a while. If you enjoy adding BJJ and escrima to your kenpo, then have at it. If you feel it adds something to your skills and your enjoyment of the arts, you don't need anyone else to validate what you are doing. If you feel that your approach is somehow "better" or more realistic or smarter than others, that's also fine.
But not everyone will agree that this is necessary. I don't say that it's a bad thing to do. But I do say that it's not necessary. You can be very very effective by concentrating your skills in one area, and learning to apply them against all others.
