[member="The Shadow King"] Pretty much yes. Any attempt to engage hyperdrive while within the gravitic influence of a planet will send you directly into the object the gravity comes from, or distort your jump so much you collide in the center of the largest source of gravity...
That's not even to mention the gravitic forces I am currently applying to your ship that should probably similarly prevent you from trying to engage your hyperdrive for the reasons listed above, as your ship will just fall into the closest, and strongest source of gravity (in case you are wondering, yes, this should interdict your vessel from leaving the battlefield until my vessel is rendered disabled, or is not actively acknowledging your ship with gravity beams).
Also, what needs to be elaborated on? Whatcha doin that I don't seem to understand?
