I was concerned back in HW when they announced they were cutting back from three dungeons per patch to two.
I'm concerned again now that we're going from two to one.

Truth be told I don't need dungeons to cap any more but I think there a lot of players that still rely on them and may not have time to sink into other content. SE seems to be moving towards providing lots of different niche content these days and I wonder if there's a large general audience getting left behind. I suppose SE has metrics suggesting otherwise.
