So I am only missing two Braytech weapons, and decided to try and unlock them so that I can get the Wayfarer title. The breakdown to get a Braytech weapon blows my mind. First off, I spent hundreds of keys on a character I didn't realize hadn't completed the Nascent Dawn quest, so despite being able to make the node keys, and unlock them, I believe it won't drop schematics for you (I understand this is mostly me to blame). Once I discovered this, I switched to the character that had completed the Nascent Dawn quest, and received only 2 schematics after again, using hundreds of keys. Both schematics gave me The Frigid Jackal, a weapon I had already unlocked. So to unlock a node I need 4 stems, which means speed running a lost sector four times, to have a chance of a schematic, which has a chance to be the weapon I need. This is a joke. Fix your game.
