Well if your Krav classes include live sparring (not point or light sparring) then it's going to be more effective than the classes I have observed. And that's kind of the issue with Krav, maybe you'll learn some useful techniques and maybe your classes involve sparring, but there's no guarantee. And if you do have sparring it just ends up looking like poor boxing and BJJ. Why not just learn the real thing?

At the end of the day, of course techniques matter, but it's far more important that your martial art incorporates LOTS of live sparring. It needs to become second nature to apply your techniques against live/resisting/struggling humans that are trying to apply their techniques on you. That is why wrestling/judo/BJJ/boxing/MT are so dominant in MMA, NOT because of the "rule-following" techniques they use.

If a guy who has spent his training learning "street" techniques that you can't actually spar with (eye/groin/throat attacks) had to actually fight someone who has spent his training applying "non-street" attacks live for hundreds of hours, it wouldn't even be a fair fight.
