What I hope they do for 6e DnD

[Anonymouswizard]

This is correct about the older Warhammer games, but the newer ones (well, relatively newer, they're pretty old by now) like Dark Heresy 2E operate on an "aptitude" system where your basic choices - background, homeworld and role - determine how easy or hard it is to purchase certain attributes, skills or talents, though each choice also has unique abilities. I'm not sure how Warhammer Fantasy 4E does it, but I think it cleaves closer to the old model.

WFRP4e is essentially what 2e did, but more streamlined. So instead of a bunch of Careers which promote you to more advanced Careers you have four ranks in your Career, but can leave and start at rank 1 in another Career.
