Now that I'm finally looking at running Paragon tier adventures in the near future (level 10 now), I have come face to face with the fact levels 7-13 really lack significant adventures in Dragon.
And really, just from reading the adventure list, it looks worse after that if you're not on the adventure path. There's a few, but man, that's something that should be addressed. I may not use adventures whole sale, but I do like to look at individual encounters to help spark ideas.
Also, I don't know what to say about Dungeon going a month without an adventure.
Maybe WoTC isn't getting many submissions?
edit note: Just saw new Dungeon has 2 paragon tier adventures listed, so that's a good start.
