The perma-cloaks are pretty much faction perks, Divine. K'hara has them, and Wild has them with the use of nomad power cells. Apart from that, the loading times of nomad cloaks are way higher than the ones of human cloaks, so they can't use them to escape from a battle but just to fly to a system without being stopped before reaching it. I don't know how the loading times of hybrid cloaks are, though.
The cloaks however are a technology coming from the nomads. They have mastered it.
But we had this discussion already when you were ranting about the Oracle cloak. Let's rather not finger at the cloaks but rather at the Cloak Disruptors.
I mean, there is literally no real threat coming from nomad cloaks. They can't escape from a battle using them, and they can't buttcloak as they are required to drop the engagement lines uncloaked, even the K'hara. Humans on the other hand are using this method very common, especially on battleships in Liberty and partially within the Core, Corsairs and Maltese playerbase.
