Dungeons just aren't considered important content anymore, sadly; it's something people just plow through for gearing for raids, maybe done once or twice while levelling to do the quests, but it's not alternate content to raiding anymore so it's falling to the wayside. Sad really, as dungeons are my favorite part of the game.
So no, it's not a lack of content overall, it's just that dungeons seem to be forcibly being made obsolete.
That's mainly because we didn't get any new ones, and the ones we had were always a roflstomp even at level. Had we gotten new dungeons with new gear as a catch-up instead of Timeless Isle, people would run them. If they made dungeons that actually made you pay attention (think Flex raid difficulty) people who like small groups would run them instead of raid. But since raiding is so accessible now, the playerbase as a whole seems to think having to create five mans for non raiders is moot, that five-mans are now solely for capping valor and only for gearing at the start of an expansion.
