The better man? There is no such thing [base class]

[Rizban]

Incarnum already has an off-class mechanic in the shape soulmeld feat, and making incarnum internal to the class could cause issues with, for instance, the Soul Evolutionist PrC.

The reason I ask is because of that class. I don't like it. It's based on a class that was made for a Magic System and honestly doesn't really work for the more physical nature of this class.

I'm in the process of reworking that class a little bit and am working on another mutation/incarnum class, though you probably won't like that one either as it isn't exactly a dual progression class.
