So in exchange for convenience JDs will offer a lot less freedom, they will become more expensive, and we don't get to go to any fun systems unless random jumps are explicitly allowed to come back later – and coordinates of such systems are no longer a thing.
This feels a tad bit depressing. Guess it's a good thing I was never invested in using jump drives. The things were too damn expensive anyway. Since I never had the motivation to farm billions to become the target audience of certain changes I sure wonder what Discovery will feel like after the patch.
