What's astonishing is that you still don't get it. Perhaps if you stopped being defensive/condescending, with some lordly above-it-all bemusement, and read and processed what some people are saying to you with even a modicum of humility, you might actually learn something and do your job better.
The problems are these:
1) You pose a question that no one gives a shit about, and then come to the conclusion that we were all at in the first place. The fact that you came to the same conclusion doesn't prove that you're on board with all the "ragers" and that therefore they had no beef -- it proves that you just wasted everyone's time with something that was inherently obvious and therefore not worth writing about in the first place. You think people misunderstood you because they didn't read all the way through. Wrong. The problem is that we DID read all the way through and realized you had nothing--zero--interesting or thoughtful or productive to say about the game.
2) Not only is Diablo one of the single biggest PC gaming franchises , but MANY OTHER of the biggest franchises--and not just RPGs-- ALSO have used isometric perspectives for decades now. You write about it as if it's some wacky, newfangled thing you've never heard about, which, sorry, makes it hard to take you seriously, even if you claim to be "first and foremost" a PC gamer.
3) You have access to a beta of something a great many people are dying to know about. There were so many angles you could have taken to write about---even as a noob who'd never played Diablo before. That, in fact, is a great perspective to have, as I'm sure many younger gamers are coming into the series fresh. But your angle is: "Let me take a totally moot point around a design decision made 15 years ago and then decide that, yep, that was a good decision after all." How in the world do you think that serves anyone, let alone the PC gamers who are your audience?
4) If you really wondered, as a journalist, why Blizzard didn't do a first-person perspective, why didn't you ask THEM? A couple quotes from the design team on that point might have actually been interesting, rather than lazy, masturbatory speculation.
5) Your analysis of why Diablo's mechanics aren't difficult *because* of the perspective makes no sense and is laughable to the many, many people who read your site (you know, actual PC gamers), who know just how complicated the strategies can be. Why the heck do you think there are 10 zillion sites devoted to the topic? Dismissing the game as "too easy" because (of all things) the isometric perspective is a nonsensical leap of logic that would be embarrassing in any article. That it comes from the editor-in-chief of the site is, to use your word...astonishing.
6) Your dismissive tweets, now followed by your second post saying you won't bother replying to any comments because you've said your piece, just shows you actually aren't listening to anyone in the first place, or care. Everyone is wrong but you. That must be a nice place to live, inside your head. Kinda sad for your readers, though.
