I don't know, seems like a meh change. Not that a lot of people care as I still don't see cloaks used much.
While the possibilities of new gameplay options (ambush piracy ?) seem nice, something feels off with losing the tactical advantage of cloaks in combat. Would have to agree that dropping powercore on uncloak would have probably been a more obvious solution with less effort involved from all sides.
Cloak disruptors will need a buff with this implemented though.
Or maybe they should get turned into something else - position scanners ? Something like a /sweep <name> command that drops approximate coordinates of a targeted name (maybe with alerting the sweeped target back, depending on the level of the scanner). Basically a form of sonar.
