Does anyone know if it's intended that Weaponcrafting Research stuff have weird unintuitive pre-reqs? Currently, the tree (and consequently the vendor) is designed in an Earth/Fire/Water/Air manner, such that you have to go down the Air tree, whether or not it's the same weapon. For instance, I've created Adventus-2 Claws, but to continue to Adventus-3 Claws, I have to first craft two resonators and a greatsword, because for some reason the 3 and 4 claws are over in the water column instead of earth where the 1 and 2 were.
So basically I'm hoping to get some sort of confirmation that this is intended before I start blowing research fragments on shit I don't need just to unlock my 3 and 4 claws. Anyone know?
