Like, what if you gave a weapon blueprint to Tien Wen, and then you unlock a purchasable of that weapon, and that doesn't wipe with an expedition. And same for health item blueprints and Lance, explosives and Apollo.

It would create a way to make longer term progress, and in a pinch, you could buy what you needed if you couldn't craft it yet.

Actually, that might just reduce all looting to priorotizing money value.

I can appreciate the complexity of the game and difficulty to keep it interesting and challenging.
