Since your settlements passively collect gigantic amounts of the two required materials, you end up being able to produce enormous amounts of Jet for a game breaking amount of caps and xp. There are a lot of ways the game's balance starts to fall down in the late game but starts to happen as soon as you have a few industrial plots collecting organic and machine scrap. I don't think there are any other vanilla crafting recipes that are anywhere near this rewarding, this early. One could argue that passive purified water collection is OP but this thing with Jet is many, many times more profitable. FYI thanks etc
