Soooooo.....Does anyone know where they buried the guidelines, rules, ideas, etc. around the alternate chargen? The whole reason why the exp cost are listed for the starting skills & talents in each career? The idea being you could mix and match builds to fit a certain concept. Anyone? Maybe...
Alternate Charcater Gen
If its 'like class x but' then use that class as a basis and chop and change the skills that you don't feel fit for ones that do (try to use ones available in the same Rank ideally).
Alternatively create a brand new class from the ground up but I think most would fit the 'like class x but ...'
Then you just have to work out the stat priority.
I think the costs of starting skills was for conversion of Dark Heresy characters.
