Need some advice with my Charged dash Ascendant

https://pastebin.com/Pne4KgYx
This is what I want to do with current stage.
It has to be Scion.
The idea is using Raider and blood dance to gain frenzy for onslaught.
The other Ascendance is elementalist.(because I'm not going for crit.)
Main hand is Tempestuous Steel for lightning damage.
Off hand I choose Bino for its physical damage.
Not sure Bino is gonna work or not.
Any advice is welcome.
