Generally if I'm lucky and I need a tier 6 stone axe I'll make it sense legendary parts aren't that hard to find to sacrifice one.
However the rest of primitive teir isn't worth it.
Who out here is making tier 6 primitive armor?
Pipe guns maybe but still it's pushing it. The only tier 0 I say is worth Quality 6 is the AR and bow. Maybe the rifle/shotgun when you get the perks
But imo tier 0 shouldn't cost any legendary parts but should cost more or maybe for Pipe guns need 1 weapon part aside from the bow
tier 1 and up? Fair enough
And possibly you get your wish. The "nevermore" could be about needing a legendary part for tier 0 purple items.
