Why was derringers nerfed?

[BaneOfGiygas]

Along the same lines as what Mageziya's saying, just look at all of the other instakill stuff (or stuff that's really close to it) that's strewn about the station and can be ordered by traitors. The gibber, any airlock exposed to space, mass drivers, the crematorium, chokeholds, crusher units, a whole bunch of different chemicals, egg+bible, man eaters, the conversion chamber (in a sense), mindslave implants (also in a sense), the trash compactor, teleport guns, trick revolvers, and all of that's not even counting the stuff that's very, very lethal, like the cyalume saber/butcher knife/red chainsaw, emagged medbots and floorbots, the hunting rifle, plasma fires, the list goes on and on and on. All of these technically have counters and/or are very situational, but nerfing something for the sole reason of being instant death seems silly when you have all of this other instant- or near-instant-death stuff running around.
