Captain Crap

Well, according to the "curve" I determined using linear regression based on current monster stats, Dash would probably be something like 77/77, Legend Hawk would be something like 75/80, and Kilothi... well, I can't really say, since who knows how important the zero sac and skewed stat balance are (one of the two doesn't seem to be factored in at all right now).  Maybe as high as 60/120?  55/110 at least.  

The amount of data available for pinning down how much more valuable a high-attack monster is vs. a high-life monster is pretty minimal, mostly based on the opinions of veterans rather than anything hard and numerical.  The value of "abnormal" sac is similarly nebulous.
