@Prime: Thanks for the heads up. I had glanced but didn't notice any.There's a "Pathfinder" section in Base Classes.
So far though, it only has the Pathfinder-specific base classes (e.g. Magus, Oracle) rather than any guides for the Pathfinder versions
of 3.5 classes, like a PF Paladin handbook. So I support this guide.
Seems to me that the trend so far is generally 3.5 or Pathfinder and not usually using both.More that they're analysed separately.
This I agree with; for a 3.P game it will vary too much based on what material the DM allows to mix or which rules/wordings take precedence over which, so better to write handbooks that treat the systems separately and anyone playing 3.P can simply open them both side-by-side to make their selections.
