K, I did a read through or two. I'm a numbers and mechanics guy so that's mainly what I focus on to start.
If I understood correctly, the only rolls that really do anything is a 1-4 on a d12. Anytime a 1-4 is rolled that counts as "damage". So I could play this with d6s and counting only 1-2s?
The Attribute values are a bit backward. The higher the attribute value the smaller your dice pool (which I understand, less opportunity to roll a 1-4). I understand why there's the conversion from the attribute values to the dice pools, it's really hard to spend points and have the result count down. However, I'd suggest using the dice pool value as the attribute instead of the current numbers. It will simplify game play.
Actually if all dice pools started at a base level and your generation points just removed a die.
Those were the first two things that jumped out at me.
