For most of us it isn't even glitches. It's the general awfulness of the combat system. See other threads for that, it has been explained a million times. Bioware LIED to its fans when it said it was making this game for the PC first and foremost. That is OBVIOUSLY not the case.
I'm sorry, I'm a PC player, never ever owned a console, and I prefer it the way they made it. I am positive there are many other customers that feel the same. I also preferred to play The Witcher 2 on an xbox360 gamepad, too. But that game had even worse bugs than this one and it took ages to fully resolve them, but everyone praises CDPR to the heavens - and for good reason, because people have distance and are able to look at the finished product as a totality.
I can understand everyone's frustrations, and it isn't good enough because the developers clearly have missed some very important technical issues. Given the scale of the game I can understand how that happens but the fact is you don't expect to go to the cinema and have the movie out of focus or having to be respliced all the time. From the consumer perspective the technical bugs are unacceptable. The rest of the complaints (Why did you do/change this?) aren't as absolutely valid as the upset parties feel, I think.
PC was their development platform (it's everyone's development platform) - but maybe playing the way DA:O did wasn't their development target. I cannot see how that is a problem considering DA:O played like an absolute dog, like a stupid MMO with one of the worst UIs ever. But even if you thought it was great it doesn't mean they broke any consumer rule by deciding to change it or do it differently. That is a valid choice for the developer. Just how I personally also think the tactical (orthographic) perspective should be able to be zoomed out almost as far as one wants and find it hard to understand why they wouldn't do that, in no way does that constitute a "breaking" of some promise to consumers at all. It sucks and I hope they fix it is not the same territory as I can't play the game or the game's performance is impaired because of bugs.
So let's just have some perspective, maybe.
With a bit of distance you realise that the intensity of a fan's frustration is roughly proportionate to the amount of anticipation the fan has for a video game. As somebody whose heart still has a bit of a fracture from the wasted opportunity that was Mass Effect 3 (it should have been delayed and released at least 2 years later and had the scale that was promised, the scale and quality that I see on display in DA:I), I think I can very safely say that that level of emotional response and investment is only appropriate for the actual game itself, not for the hype of it. It's just not good for anyone to be pre-invested in a consumer product no matter what it is. It's just a silly, unhelpful, and unworthy thing for any human being to do. It's just a waste of energy and produces extreme reactions to a fake thing that only has the meaning you give it. To give it any meaning separate to the actual experience of playing the game is a wrong thing to do, no matter how induced you might be by a games publisher. I say this as a former addict to this kind of thing myself.
