Personally, however, I don't think it's helpful to just drop a video link with an unhelpful title without any grounds for a discussion. I am not particularly interested in listening to a thirteen minute video (I would prefer to read an essay, but that's just me) trying to figure out what you're getting at.
In a nutshell for those curious, the video goes into the question of asking "is theorycrafting ruining MMO's?" where playing a game to be as efficiently as possible means you've "skipped the game." The video discusses the nature of how many games have the element of discovery and surprises in games and how many games now have a "post-information age" state where there are guides, tutorials, and potential mechanics/gimmicks all documented, theorycrafted, and explained to a point where it becomes a detriment to not know what is already so available.
In the case of how this relates to New Genesis, I feel the main problem is that the core gameplay loop (the guruguru fields) all hinge on randomness or the alternative of picking up the loot instead from the Personal Shops. There is no complexity or depth in a lot of the classes and gameplay (at least to me) that requires mechanical depth and technical depth that you practice and perfect how you want to approach the game. I don't think guides that players made for classes or how to approach content like grinding equipment are bad but I do believe there is a time and place for the people who use theoretical numbers to shine and a place where "playing the game" really should simply shine. Thankfully, New Genesis does not have the same situation that Phantasy Star Online 2 had where you can't exactly "mess up" your characters and your decisions without a grind (if you make a multi-weapon you regret, you can always make Meseta again later but in the original Phantasy Star Online 2 a poorly configured skill tree is not something you can correct for free due to the nature of the game's support now).
I don't feel like you can win the fight against players who will speedrun the game (Phantasy Star Online 2 is notoriously easy until you hit a few walls in specific quests and everything that was hard at some point was simplified to be easier outside of the final Emergency Quest) or players who try too hard with what we have but I don't think it's their fault they like to push the envelope on something that can't really be pushed when there is not much distance to push towards.
I think you missed the main point of the video and that is, community cohesion. In the video he states why the speed runners approach the game the way that they do and it is to gain an advantage but then shout that their is no content to push the same cycle with no regard for those who don’t want to or can’t. Then (Some not all) push the narrative that their isn’t enough content to entertain the community under the umbrella that the game is going to fail because of this inflated issues. Which is an attempt to boost their personal agenda on their content platform.
