I'd be willing to argue our opener isn't where most of our damage is anymore. Nastrond is what we want and B4B is up by the time we hit that phase and it seems (from my experience) we have a "2nd opener" there. Hungry Eyes isn't available then granted, but it helps buff other melee who frontload more heavily.
Edit: I also glanced at your savage gear build and it seems viable, but I'm wary stacking that much crit currently given the small returns. I posted 2 a page or two back using the new info from Dervy but without further vetting I'm unsure what we should aim for. For Vit, I think that was only for 12S really as you would take unavoidable damage and, at first, it was damn near impossible to survive. It does help, but I'm not sure of any fight in 1-4s of Omega where we have similar.
