Tasers are bad. Stun bullets too.

A traitor is a dangerous guy with license to kill...
...if you go alone against a traitor you shouldn't have the upper hand...
...and if you want to beat up a traitor you can just go vigilante.

This seems to show a mentality where traitor = rampager = fun, and anything that can possibly stop rampages = unfun. Very rampager-centric.

IMO the traitor seems to be primarily designed as an assassin and saboteur, not a space rambo. Assassins excel at killing people at unawares, but tend to be disadvantaged in open combat.

While I do think one-shot tasers are too much, 3 shots with the first shot being utterly useless is not the way to go about it. All it is encouraging is for Heads and Security to use lethal force with worrying regularity, and that's not good for anyone.

Again, my suggestion is to make the first shot slow and the second shot stun. That should nerf tasers without encouraging Security to ditch it in favour of lethal weaponry.
