What? The Scaevan weapons are there. I bought a GNB one myself. Can't speak for anything else though.
This would make sense since they've made it their mission to get new people into the game with Shadowbringers. Allowing some of them to be crafted a few days early would give some people a leg up on those who have yet to set foot in this expansion. So...here's hoping.
They add a Coven weapon (aka diadem rng weapon) but no Alex weapon
