See no ripped people in crossfit? Well, your sample size might be too small or biased! Sorry for the statistic talk, but that's true...
You've correctly mentioned the functional aspect of crossfit. Bodybuilding doesn't really relate to a healthy lifestyle (imho).
However gaining muscle mass doing crossfit...not the best thing, but it does depend on your starting point.
My advice. Stop collecting other people's thoughts here and just give it a shot! You might totally hate it or...fall in love with it.
