Not at all!
Having full body explosions occur on every kill vastly overstates the power of the weapon while reducing visibility a lot for other players with the gore and blood clouds.
We are working to fix the bug so the damage and targeting of the Surge staff and Smite returns to normal. Alongside this we will add that critical strikes will guarantee that the enemy chest will explode, adding some of the gore back in.
Assail crystals and the Melee power attacks I will have to investigate separately
