Tasers are bad. Stun bullets too.

Wrong, every time security wins all the fun gets killed.

If this doesn't show an overwhelming bias towards rampagers I don't know what does. Sure it's not not fun for a rampager when his brainless murder spree gets stopped, but it isn't usually isn't fun for random crew when they get permanently taken out of the picture by a brainless rampager either; and generally the victims of a rampage outnumbers the rampager.

A large component of fun is unpredictability, not knowing how something will turn out. You seem to believe that when rampager meet Security the rampager should always win unless greatly outnumbered, which with the few people willing to play Security (even less now) doesn't happen. What you seem to want is for your rampager rounds to be carefully choreographed, rather than risking a good chance your blatant obviousness backfires.

If you want to rampage then you should be ready to take risks or preparations (meth anyone?). To expect to rampage without significantly more risk is unrealistic, to demand change to this effect is selfish.

The fact of the matter is, rampagers are the most common type of traitors by far, far more than stealthy traitors and assassins. Whatever you try to claim to the contrary Security is and has never been gravely overpowered, certainly not to the point where there's "a mentality of poor rampagers being afraid to do anything if they aren't stealthy with three backup plans". I agree that one-shot-stun tasers make gunfights uninteresting, that's all I agree with.
