Tasers are bad. Stun bullets too.

[Karakoran]

A traitor is a dangerous guy with license to kill. Taking him on alone is a bad idea that is not guaranteed to succeed.
You want to raise your odds? Get help from bystanders, use flashbangs (try not to stun yourselves, eh). There's more to playing cop that shooting pew pew with a taser.
Traitors, on the other hands, are going to be fighting against a mob most of the time; the last thing they need is a mob with better guns.

Maybe raising the taser's clip won't be catastrophic. But complaining that it isn't efficient at stopping traitors is failing to understand that: A, the taser is not your only weapon. B, if you go alone against a traitor you shouldn't have the upper hand.

On a separate issue, if you think people don't play security because the crew is hostile and the weaponry insufficient; think of all the dull rounds you played when there were no overt traitors, or when the crew mobbed them before you got your chance.
Patrolling the station is a boring occupation compared to most other jobs, and if you want to beat up a traitor you can just go vigilante.

Except half the time there is only one security guard and there's multiple antags. Plus if a traitor ever finds themselves actively fighting a mob then they deserve the beat down they will probably get. Aside from maybe having to fight two sec/command guys at once, they'll usually be picking people off one by one.

Not to mention the taser IS your only weapon as security, at least ranged. Unless you're throwing flash bangs around so you can end up stunning everyone involved, you're useless in any ranged combat.

I can understand not wanting to make it too hard for traitors, but they have tons of advantages too like being hidden, plenty of gear, a possible second chance after getting brigged, etc. Even with the best taser they still have the advantage in a one on one fight. If anything all a weak taser does is make rampages all the more easy. Fighting a guy with a laser gun, for example, is impossible with such weak tasers.
