If your using EtZ or D&Z Essence becomes a big Issue.
Not just another way for Norms and Survivors to get whacked. :D

It would also be nice to have a Book able to work in both systems without having to convert because you do hit some Bumps (like Essene).

I think Skeloric is in on this one (although I don't despise Cinematic):p Cinematic has gotten a lot more attention and thats only starting to change now.(ATZ,ATBZ,Con X 2.0).
Just my opinion:D
