add old nuke back to rotation

[Roomba]

Or one syndi would rush out alone at round start and kill the captain before they even left their office, get the disk, and set the nuke off within 5 minutes

This was basically the issue with old nuke. The fact that it was possible to lone-wolf it meant that that was all anyone would ever do. Actually trying to communicate with your team members was a futile effort at best and liable to get you shot at worst. All anyone would ever do was rush for a suit and jetpack, rush for the cap's office and attempt to take him down 5 minutes into the game. Half the time this meant that the round ended four minutes in, before anyone else got to do anything. The other half of the time the opening charge failed and it just resulted in the syndies giving themselves away and tossing themselves at the crew in a futile effort, causing the round to drag on forever.

Incidentally, the worst offenders all seem to be the ones clamoring the loudest for the return of old nuke, for some reason.
