It is good that things in the actual game seems to have calmed down a bit. An experienced player in Pathfinder can create some monsters, and generally the more like a monster (as opposed to some kind of human) the character is the stronger they get!
Stacking armor and natural armor is a primary source of ridiculous AC values. Not letting them stack may be a little unfair, though, since small amounts of natural armor are rarely a problem. If that situation comes up in my games a lot, I would likely declare that only half the lesser value applies to AC (i.e. +6 armor and +6 natural armor = +9 to AC rather than +12).
