The vendor is broken, players should not have to nerf themselves or "avoid" features just because the game developers couldn't balance them right.
I am so sick of this idiotic statement that gets repeated like some sort of wisdom around here. By this "logic", they should remove Caravan too. I can make thousands of caps in minutes if I choose to.
"OMG, there's something that I don't have to use, but when I do out of my free will, it makes the game easy so it's all broken herp derp"
Exercise a bit of self control. You actually have to go to the Bunker, collect the chips, go to the machine, and actively select what you want. If anything, you're not
not avoiding game features, you're going
specifically out of your way to (ab)use them. Don't blame the game, blame yourself.
