Best in slot belt for shamans along side Belt of the Fallen Wyrm
In my opinion Blue belt of chaos is better because of the 3 gem slot bonus and more crit.

shamans who stack haste for chain heal would go for the Belt of the Fallen Wyrm. But crit is more important for the LHW spammers ( which is more HPS anyways..)

Also added a few screenshots for those who are interested.
