I, for one, don't buy OP's appeal to authority. I frankly don't care at all about what is IH saying, the stuff he does not talk about is far more interesting. But I get it, the guy has to protect his (very well paid) job, so if his boss(es) tell him to spout trivialities or outright nonsense in front of the fans, he complies. I've been following IH's statements for a couple of years already, and he never had anything of value to say except maybe "leveling isn't in a good spot" or "legendaries aren't perfect".
I'd love to hear him talk about the reasons that brought him to saturate the game with RNG mechanics. Or to timegate the hell out of new content (Broken Shore anyone?). Or how they deal with outsourcing, since every new patch breaks the game. He is a terrible communicator at best, and a corporate zombie at worst. Imo he should have stayed designing raids, which he rocks at.
And since OP didn't bother to provide a single example in his essay, his post comes to me as pretentious and utterly condescending. I see why he likes IH.
