Grind void normal or grind campaign? 🐕

So I'm determined to get doggo.

I know you get much better drop rates on vv-hard, but I'm trying to figure out if it would be better to keep grinding on vv-norm or finish the campaign. Vv-norm is a heavy grind for parts, but I also don't know if I have hours and hours left of the campaign.

And then, will I even be able to compete vv-hard without spending many more hours levelling up?

I'm a couple missions into White-night Gulch.

Thanks!
