It's filler until you can get your hands on the higher ilv blues. As others have mentioned, its value is at its highest when the patch is released since access to the blues is gated. Sometimes, blues still carry unfavorable secondary stats that could possibly throw you into a different Speed tier, and/or some will see a favored secondary stat such as Crit rate take a huge hit by switching to the blues. While those losses are kind of a bummer, the loss to your primary stats by staying with the crafted gear when you have access to the higher ilv blues is a no-no in most cases.
