I wasn't just referring rules changes. I'm talking the day one erratta that most books needed because they didn't edit them properly. The way they changed powers online like it was a video game is another thing.
This wasn't anywhere near as bad as you claim.
And if we're going to talk about needing to errata things because they weren't edited properly, I'd like to introduce you to a thing called "Pathfinder 1st edition." Which had such editing
gems as Prone Shooter (which removed
a non-existent penalty before it was errata'd) and Death or Glory (which forces you to trade away your whole turn for a
single attack, only against Large or larger enemies,
and you pay for the privilege by letting the target get its OWN,
buffed attack against you). Or the problems with Gunslinger that would cause it to misfire more and more often per turn as it gained more attacks, a thing that got people outright banned from Paizo's forums for pointing it out.
And that isn't even talking about stuff like Shadowrun, which is openly notorious for being full of typos, bad editing, and more, which doesn't even get errata in the first place.
Do you have any actual, concrete examples? Or are you just engaging in partisanship for its own sake? We know about the errata for stealth rules. (And guess what 5e also got!) What, exactly, was the horrible awful editing that was so desperately needed? Because I own the books, and have read them extensively, and don't recall such horrific problems in the text itself.
Finally, I'm not going to dignify the "video game" comments with a response beyond this sentence--it's crass name-calling with literally no thought or content in it, and even this response is more than such an argument deserves.
