I would like it if some of the beliefs more closely modeled aspects of real-world religions, but I have the impression that Firaxis was deliberately trying to avoid this in Civ V. Setting up models of religion that allow some to be shown as demonstrably better than others (which is what the article author seems to be asking for) is dicey political territory.I dont quite agree with the article but it would be nice if we had some base beliefs for every category but some other options showed up depending of whats going on (ie Messiah option shows up if you are getting your city conquered and it makes your soldiers or cities stronger or w.e.)
It will be interesting to see how Religion evolves in Civ VI. I do like that there seems to be a greater variety of icons, etc.
