I dont know how well this will work in a dh2 setup. So much depends on xp purchases and that depends on dieties, not aptitudes which I actually agree with. It should be easier for Slaneesh PC's to buy stuff that would apply better to slaneesh's skein, and not totally based off aptitudes.
Im going to concentrate first on pulling DW creation into DH2. Then Xenos possibly, then this. But im open to any ideas you guys may have.
