Add a short cooldown to the traitor invisability cloaker.

Isince the only real tactic is running around popping it every now and then

Or moving in a group and popping them when the invisible man attacks one of your guys?

This is less than optimal since it also stuns your other guys unless you also have sunglasses (which are almost exclusively held by security) or welding masks (a bit more readily accessible, but still somewhat limited).

The point I'm trying to make isn't that there aren't enough flashes, it's just that just about all pieces of traitor gear have counters that are available to everyone. Typically that counter is in the form of robustness, which tends to be an equalizer in most combat situations. But you cannot be robust if you do not know that you are about to be robusted, so unless the cloaker is hideously unrobust or messes something up, you cannot rely on your robustness in most instances. The deck is stacked in the favor of the cloaker, and everyone else has to find a way to neutralize it. You also can't really figure out where the cloaker is using keen observation skills, the other equalizer in these situations, because it's just about impossible detect a cloaker unless they mess something up at the wrong time or the AI can and is willing to track them.
