well height and weight ARE notable because if the rp is combat scenario based roleplay weight class and how tall a person is drastically effects how they can do some things. Why do you think you rarely see heavy weight boxers fighting feather weights? Because it'd be the big guy smacking the smaller guy around a hell of a lot or the smaller guy just dodging and weaving around like a devil for the most part. Also it is notable if a character is taller than the other for reference sake.
