It's been datamined that Fist Weapons exist as a weapon category, as well as 2 other Flashpoint/Operations, not to mention all of the multitudinous enhancements and mods that exist artefactually but can't actually be gained. Just because it exist in the code somewhere does not meant that it exists within the confines of the game. It just means that, at some point in development, it used to exist and no one bothered to completely clean up the remnants.
After reading this all I could think of was:
"Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force."
XD But in all honesty, Kitru's right. Just because there is something lurking in the code doesn't mean it's actually there for an intelligent reason.
