Nothing is bad from getting something for free .. 60 and 30 frags is not bad at all, just don't mind them to the extent that you will feel mad about it .. Let it be, go and stack up high in your ninja den, one day you will end up getting that ninja to 5star and then their fragments will be useful for Refining Fragments or if they have skillbreak then exchange it to skillbooks .. And if you have enough luck and get AsumaWB or other ninjas that are currently in the basic teams then congrats, if not, better luck next time ..
