While I accept that autostrut and/or eliminating all wobble is not "realistic" as far as the physics is concerned, I think it's important to remember first and foremost, this is a game!
Building ambitious/ridiculous monstrosities is part of what made KSP1 fun and while we all expect and enjoy the occasional explosion, the game needs to be enjoyable. I would mirror those who say that if wobbly rockets were not an issue, autostrut would never have been introduced as a feature. Nor for that matter would it have been so widely used.
Wobbly rockets are just NOT FUN! Funny to look at, but a hideous barrier as far as gameplay comes. I think Nate Simpson is missing the point when he says "Wobbly rockets are sometimes fun and funny. A big part of what originally got many of us hooked on the original KSP was the silliness and emergent problem solving that came from playing World of Goo with rocket parts. Broadly, we see this as part of the Kerbal DNA, and want to preserve it in some form. " Yes, they were part of Kerbal DNA, a part that was eliminated as KSP was improved over each subsequent release. KSP1 when released was the plucky outsider, there were problems and there were bugs, the community laughed, because it was the plucky outsider. Wobbly rockets were never fun. We laughed at them, sure, just as we laughed at the Kraken tearing apart our carefully constructed crafts at the end of a 20hr mission. ...but they weren't gameplay features! They were annoying!
KSP2 is not KSP1. KSP2 launched at £49.99 and had been in pre-production for years. It is no longer the plucky outsider and while it may fall short of AAA status, it's a lot closer than it's predecessor. It should have been playable at launch and my tolerance for these types of bugs is therefore much reduced. The fact that the entire community is calling out for a fix to this issue should be an indicator to the devs that we do not see this as a feature, nor do we particularly want it as a feature.
The game should be fun for budding aerospace engineers and casuals alike. KSP core mechanics are what makes it fun. While it should be a challenging game, we are not looking for gritty realism, we are looking for a fun time.
