In the video you say that the pierce is kinda high cause of Elemental wisdom and thats not true. Its high cause of Sanguine covenant. I think that skill is an overkill since you can easily get 140-150 pierce.
I would recommend Crafted weapon (with cata or magic missiles on attack) and crafted shield over that RW. The RW is definitely a cheaper option, since you need to sink a lot of shrines into crafts. The RW is a better option single target wise if the target isnt moving too much ex. Riftwalker and dealing with the big guys in Scosglen.
Radiance setup isnt optimal as you lose a lot of spell damage and spell focus compared to having 2x ras alghati + rare 3-4 skill amu and crafted helm/Veil of the Tainted sun SSU. You dont need the pierce and the phys res from Radiance as well which devalues it even more.
One minor complaint about the video from me is when you were showing the stats you didn't show the damage of blood thorns fully buffed. I had to pin point pause the video to see it when you hoover over your skills. Other than that- kudos and cheers.
