In many well-known ways I don't have time to list. Just for one example, which CR 4 creature should be harder to turn, a vampire or a zombie? (Now take a look at the CR 4 vampire and zombie.)
I remember Sean K. Reynolds writing a blog about these turning rules and pointing out that at low levels turning is okay, but mid to high levels, forgetaboutit.
I've never dwelled on inconsistent rules too much myself so I have nothing to really note. My gripes with games are more of the experience aspect as opposed to the rules aspect.
