Again, I agree with essentially most if not everything she's had to say in the video. You summarized what she had to say and she put them more refined and detailed than I will here.
I've discovered, too, that I'm definitely a midcore player that just naturally leans towards more difficult content, I revel in the chaos. Endwalker's fatal flaw is that it does not have this content for reasons Zepla mentioned.
Without it, there's only two separate extremes: piss easy casual and break-neck hardcore. There is no medium difficulty that actually helps players try to get into harder content. Eureka and Bozja fit this bill, especially when you include the likes of NM's, Critical Engagements, CLL, Dalriada, Baldesion Arsenal, and Delebrum Reginae. However, that isn't here this expansion.
I'm of the same mind when she says she expected for Variant/Criterion/Criterion Savage to be Casual/Medium to EX/Savage and not Casual/Savage/Savage to Ultimate, and I'm of the belief most other people did as well. Criterion had the potential to be another form of medium difficulty content to help ease people into hard-core raids, but they missed the mark miserably by both making it too hard to perform that purpose and excruciatingly lacking incentives BOTH releases so far.
Eureka/Bozja were something anyone could go without the requirement of going in with a group every single time, and always have something to do and gain. I do believe that loss of exp/whatever progression system in the next field zone should not be included in as well. That seems to be a common complaint even if it doesn't bother me that much.
Relics, in my opinion, are the epitome of casual content with incentive to go and do without involving high-end raiding and such. You had to put in effort in prior expansions, so that you felt accomplished when you obtain it. That's gone as well, there is no sense of accomplishment with the manderville relics because of it literally just being a glorified tome weapon. It's even easier to get than the tome weapon because it only requires the prior tome currency, not 7(reduced to 4 later) runs of the latest last-fight of the raid tier and 500 of the current tome currency.
I also appreciate her actually putting in the effort to ask casual players on their input and opinions, it helps open my eyes to how varied their time is spent (obviously differs from person to person) as well as other people who may not actually have thought that openly otherwise.
