Krav Maga is grossly overrated. I don't need to pay someone to tell me how to kicks somebody in the testicles. (Ouch).
If that's all you think of KM, you should train with someone who trained KM at Wingate sometime. In a no rules fight to the death, I don't know if I have met or trained with anyone I would want to face LESS.
McDojo Krav Maga is probably almost as useless as McDojo Kung Fu, JJ, TKD, etc....maybe slightly less uselss, as it teaches effective defenses early on in training to standard "street" attacks...but my point stands.
JMHO, of course.
