You have an issue with people not sitting around to die? It sure seems so. Anyways, I'm not sure how you're having a problem. You say nuke, that's not really helpful. Does that mean sparklies? Or the ball of doom? Either way, that build shouldn't really kill anything. Nukes without drain pulse do very little, especially versus the ships you play. How do you counter it? Shields. If in the voro, stasis pulse works too if they get close enough (which you have to for sparklies). if in the star destroyer, disrupt them optimally before, but after they attack works too. Drain pulse works too, so they can't escape as quickly, or scrambler so it's harder for them to navigate to safety. Alternatively, call them out to your team and have a vette kill/disrupt them, or an arty stasis/kill them, or a tac purge/kill them.
Also not sure why you have such an issue with scrambler. Imo it's the least dangerous pulse, drain and weapon pulse both get you killed much faster. Scramble just makes it harder to see, whoop dey doo. Lets all just be honest, you spend more time complaining about corvettes and destroyers than trying to figure out how to counter them.
