I directly quoted the parts I was replying to. You said the amount of content into each individual or 'mini' patch is shrinking, so I said that is not meaningful. They just shifted the distribution around; the meaningful comparison is the whole patch cycle.
I'm not sure it's an opinion. Isn't it just a fact to say the overall amount of content is the meaningful metric here? You can't pinpoint one random day and say the content released on that day is representative of the state of the game. One date might only have hotfixes, another date might have content. So we look at each 3-4 month cycle as a collective and evaluate that. I don't think we disagree with each other on that, just a misunderstanding.
The number of floors is just a design choice, somewhat informed by player feedback of wanting to get to the challenging stuff faster. They could generate 700 floors if they wanted, it's mostly just a question of how much repetitive filler should there be before the hard top floors, how long should runs takes. You're right, the story was better in PotD, more developed.
MHW collab content was created by the same FF XIV dev team as the other FF XIV content. I don't see why we should pretend it does not exist when discussing the amount of content being released in a certain timeframe. I'm just trying to give fair credit where it's due and dismiss falsehoods about the devs getting lazier over time. The quality is subjective but if we're discussing quantity of original content, I don't think it's accurate to say it's falling off in a significant way as the cynics suggest.
