This is exactly where I'm at as well. I started FFXIV quite late on, so I managed to catch most content in one continuous experience.
I still have strong memories of HW, SB, ShB & EW for certain scenes, characters, locations etc, even though there were odd parts I wasn't a fan of, or felt a bit slow (Post SB did this especially to me). Even ARR had segments which I really enjoyed as a new sprout completely oblivious to everything.
But DT hasn't really done anything for me in terms of feels or emotions/experiences. Even throughout the MSQ or afterwards, I genuinely couldn't care less about Tural, S9 or it's peoples - both places which should be something super exciting to visit/explore.
On the character side of things, the Scions for the most part felt shoehorned into the expansion, somehow turning the character personalities even more one-sided. Yshtola/Graha being present solely for fanservice or MacGuffin reasons, Alphinaud there to recap conversations, or Alisae to either act tough or be the Wuk Lamat fangirl. At least Estinien had the common sense to go do some casual adventuring. The new Tural characters I couldn't even tell you most of their names, outside of the main cast.
Hell, the Wachumeqimeqi quests had better writing/characters than the MSQ, I was far more invested in Shunye's Apothecary storyline than the MSQ which is pretty sad.
I started 7.1 at the same time as a couple friends so we were on track together, and we still can't bring ourselves to complete it even for the expert roulette unlock, we really just aren't invested in the story or it's characters at this point :/
