Patches being common is not a good thing for us gamers. It only means that companies think they can have it any way they wont. And a large open world can't be an excuse for any kind of bugs. Maybe for some quest related things, or something, but this argument is drawn too often.
Games are huge these days, mucho complexo. Back in the day, a game could release with a few bugs, and they wouldn't be game breaking, nowadays we have games that have so much content developers couldn't possibly find every bug and fix, especially before release.
Did you know, you could have 40,000 lines(this would be an amazingly small game) of C++(a programming language) that wont do a damn thing if you forgot so much as a single semi-colon? Imagine what bigger mistakes do to games.
tl;dr patches, specifically day 1 patches, are nothing to complain about.
