True, but the point was mostly that in this case, it's extremely apparent that there were 0 QA checks before they released it or they simply don't care. As someone who worked in QA, I can imagine them missing a lot of bugs that are happening on Remix or the main game, because they could require some obscure combination of finished past quests and an account state that can be hard/impossible to properly test for all cases, while also having millions of players, so some may encounter it.

But in the case of a major class campaign quest being impossible with 100% repro rate, because it needs items that are not even in the Remix, that's inexcusable. It's also easy to fix, and should be marked as critical because it's a progress blocker. The only conclusion is that they either didn't know about it, or just don't care becuase they know that the community will just suck it up. It shows extreme disrespect for the players. Hell, when Remix released, you couldn't even finish the first quest and if you tried re-logging, it didn't let you login. It was extremely broken to the point of being unplayable for the first two days.

I've had similar experiences even in retail. Just getting through the main campaign of last patch required re-logging to unstuck a quest 4 times (which I specifically counted), not to mention the desyncs.

I could understand something like this if it was a developer that doesn't have the resources, but Blizzard has and had in the past, but they decided to reduce quality just so they can increase their (already astronomical) profits.
