Critique my Prisma Grakata Viral/Slash Crit Build

[Kemenril]

So I was really struggling with the Viral/Slash setups when I was adding slash damage via mods and status, trying to up its proc chance by making it the biggest number, but also getting Viral on the board. So I reinvented the wheel (yeah I know there are a lot of these builds) and made this: 

LINK TO WEAPON

Got lucky with the Riven -- it's perfect. 

How will this scale to 100+ content? I've run a few sorties with this but it has struggled a bit with Infested. Generally though, I am loving this dakkadakka setup. 

Any constructive thoughts would be appreciated.

Seems like a pretty good build to me, only thing I can really see you doing is maybe trying to roll for an even better riven that has - impact so you proc slash more consistently.
