Slight rant ahead:
I'm sick of these game designers, namely Monte Cook and now Mike Mearls, gesturing towards this hey-day of 2E. These sort of comments against player empowerment, or how dare they write consistent rules for things, just piss me off. Hell, I played the shit out of AD&D, but it was an extremely frustrating system. I remember moving onto Rifts, of all things, b/c it had better rules.
And, I feel like given that the 4th Edition team managed to essentially derail the juggernaut that was D&D and massively fracture the market, they are constantly either (a) letting nostalgia run away with them or (b) trying to argue that you don't really need a decent game, this magic DM figure is supposed to paper over everything they fuck up at the design stage.
