Yeah, I don't understand either. I tend to use either Seleukos or Atargatis for my temple lines, Seleukos inland and Atargatis for coastal. I've never had anyone from Seleukos go anywhere past "Hates the Gods" which should be the +2 unrest one. Atargatis however....yeah. Maybe it's just me, but do different temples give different traits/ancillaries to your characters? The Temple guide doesn't really specify on those and I don't have the technical know-how to look them up myself.
