Why was derringers nerfed?

[Dabir]

Let's talk cost efficiency. The purpose of the derringer, from what I can tell, is to make someone drop the fuck dead. While technically with two uses, it functionally has only one use. It is designed to kill. Making it "fair" utterly defeats to purpose.

Now, let's talk parallels. A poison bottle only costs 1 TC, though often requires a 5 TC sleepy pen for maximum effectiveness. A poison bottle can hold enough poison to directly kill 0 to 8+ people. At optimal efficiency, plus the sleepy pen, a poison bottle ropes in a whooping 1.333 TC per kill. While the poison roulette and decreasing cost efficiency with multiple poison bottles justify the 1TC price, but that's just an example of kill to TC price ratio.

You get 3 shanks with a scalpel from a poison bottle, each dip consumes 15 units and puts 5 units on the scalpel. If you get one of the many, many poisons that Just Kill You from five units, like space heartworms, or one of the three kinds of initro, or pure bacon grease, or nanomachines, or prions, that's 0.333 TC per kill, and that's when you're wasteful. A derringer gives you one guaranteed instant kill, two significantly slower ones if you're willing to push your luck.
