I read
@Campbell's post that you quoted. I don't agree with him that 4e was "really bad at being Dungeons and Dragons " D&D is multiple things. It certaintly includes B/X and/or AD&D dungeon- and hex-crawling, and I agree that 4e is bad at that. But D&D has also, both in presentation and occasionally in the details of play, aspired to heroic fantasy. The Foreword to Moldvay Basic is a classic instance of this in terms of presentation; and an adventure like Speaker in Dreams (3E original series of modules) is an instance of an attempt at making heroic fantasy the heart of the play of the game.
There is a strand to D&D - monsters not just as HD-based challenges but as manifestations of a conflicted cosmos; PCs as heroes, sometimes super-heroes, who will save or transform that cosmos - which 4e was exemplary at.
