There is no defining GOOD scores. I, and probably several others, have made characters who have nothing in attack or block and get by perfectly well in combat, be it through magic projection, psychic projection, or using defined attack and defense ki techniques. But for those primary abilities I would say 60+ is goodish at level 1, you can push it up to 90 if you are a really combat focused character. But from then on it is completely player preference. I myself take pride in building some really weird characters, but this is really a thing of personal opinion. HOWEVER, if you are new to the game, as with your players ((assumption)), 60+ is good at level one. It is suggested that you at least be getting a +5~+10 or more per level from DP/Class bonuses. This is just my speculation on balancing a character. Anyone else willing to give their input is welcomed.
Edit: Also, if it isn't already obvious. Choosing one defense is better than going with both, mainly because it stretches DP to thin.
