The writing staff lives in a completely isolated bubble, and it seems to be intentional. Also, while BC was more or less a mess, and WotLK had plenty of "WTF Blizz" moments, the narrative was at least largely exempt of Mary Sue's, something I find extremely irritating. Thrall in Cata was cringey enough, but things became even worse in MoP, with all that preachy tone that has impregnated the narrative ever since.
