Area Effect Jump Drives, Interdictors
Change Jump Drives to area of effect devices.
Obviously this leads to Jump Drives to be used offensively, but increased power costs could be used to balance this out.
This could allow Jump Drives to jump not only the current vessel, but nearby vessels as well. Small area Jump Drives could remove a small portion of a large ship as an escape pod.
Jump Interdictor devices could be used to “lock down” areas, preventing a jump drive from affecting the area within it.
