Add a short cooldown to the traitor invisability cloaker.

[BaneOfGiygas]

the only counter against it was thermals which basically just made it completely worthless against the 2 dudes on the station who had thermals and completely unbeatable for the other 40 dudes who didn't.

I think that this–the availability of counters to the cloaker–is one of the bigger complaints going around. As far as I'm able to tell, there are three counters to cloakers: Robots, thermals, and flashes. The problem is that the first is notoriously unreliable at times, the second is ludicrously scarce in almost all cases, and the third is only marginally more readily available and has decreased counter power anyways.

The problem isn't that the cloaker has no meaningful counters, the problem is that the things you can use to counter cloakers aren't something that can be acquired by a majority of the crew and therefore leaves them as sitting ducks.
