I'd like to know the tech level of what we're using and whatnot. Reading a bunch of legends stuff SW tech does change through the years, although admittedly not by much.

There is also no reason to limit force users, as a single WW1 era conventional weapon can slaughter legions of Jedi and Sith up to and including Vader levels of power. And this weapon type would have great issues with droids, giving a great power triangle if PvP is ever a factor.
