Qarn..

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.

Alternatively, since ARR the devs (not corporate honchos who have nothing directly to do with the game design, but the actual devs responsible for dungeon content) have noticeably dumbed down dungeons. This, in turn, has led to many dumbed down dungeon-runners.
