The lack of progressive evil.
The primary evil nations of Cheliax, Geb, Irrisen and Nidal are all working on internal things or settled and don't seem like they're going to be out and invading in any foreseeable future.
Most of the great evils are contained or otherwise unable to act, an actual demon lord has made a presence in the Worldwound but is locked in, Rovagug is imprisoned, Tar-Baphon is locked away. The Runelords are asleep.
I realize these exist so you can make plot threads with them, but maybe I'm just too used to a metaplot or something. It just seems like the world is...static.
