Nah, some of the early ARR dungeons are a little wonky, and because of that SQEX streamlined a lot of the later stuff.

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.
