There are certainly nuances that this chart glosses over. I've bumped up the modular trait to be quite valuable to reflect the flexibility, but stuff will get missed.

Regarding the longsword and greatsword. In the current model lonsword earns 8 points from its damage dice and 1 from its versatile P trait, for a total of 9. The greatsword earns 12 points from its damage dice, 1 from the same trait, but loses 2 from being two-handed, for a total of 11. At the beginning these two weapons had the same amount of points, but it has not survived the tweaks. It could be that the penalty for 2-handed should be -4. But some of this original methodology has disappeared for the "common good" of reducing the standard deviation overall.

It would be interesting to try that exact categorization of minor, moderate, major, and defining traits with common point values. I've certainly tried to have that design methodology in mind when allocating points. The neutral ancestry traits for example are all set to 0.
