That being said...QA allowing a patch that makes graphics WORSE is unacceptable. The hair settings weren't a major issue before - I'm not sure why they felt the need to mess with that, specifically. Given that the patch has an argument toward making the game unplayable, it wouldn't surprise me to see a few QA people looking for new jobs after this one. This issue affects every PC user (I don't believe it affects consoles) - it had to pop up in testing.
I don't think anyone is getting fired, because I have the impression that that was their intention, lower the graphics to solve stability problems asap because of the amount of community's requests. I believe they rushed the patch and that was the quickest solution they could find, that's why they now have to give us a hotfix, do you really think they wanted to work twice and make a patch AND a hotfix? Well, if they didn't mix the patches and gave us (PC users) the wrong patch (console one) as some think (and so do I), they intended to lower the graphics, period.
The hair is in the patch notes, they probably didn't test it in the high quality, that's why they had to put the hotfix out, but the grass, the fog, and all the rest of the graphic quality lowering CAN'T be a mistake.
They now face two really bad situations:
1 - If they tell us the graphic issue was not intended, they are telling us the QA team is terrible and completely blind OR;
2 - If they tell us the graphic issue was intended, they are telling us that the dev team is bad and have no better solution for the stability than simply lowering the graphics settings.
There is no plausible explanation I can find for this so far. This is not a rage comment, so you know, I'm just trying to find a reason for this...
