Nothing Manacles should have never been nerfed to begin with. But Scatter Grenades are still pretty good with them. Just not as much as they used to be. I would know because I always use them. And Firebolt isn't OP either. Viking Funeral is OP only because of how long it makes the burn last. It would be fine if the Firebolt burn perk combo did the same amount of total damage but over a shorter period of time. Being locked out of combat for 10+ seconds is nonsense.
