Nah, some of the early ARR dungeons are a little wonky, and because of that SQEX streamlined a lot of the later stuff.
Quarn throws a surprising number of new mechanics at players, but not only do they rein in how much new shit is thrown at you in later dungeons, they also do a better job at designing them so it's more apparent what you need to learn / do.
The ones that'll probably make you saddest in this respect are Quarn and most of the level 50 optional dungeons.
