Or perhaps the possibility of smaller ships (<400kT) to land on planets even, while larger ships need to stay in orbit. Really huge ships (>10MT or so) can't even enter orbit for fear of plummeting in the gravity well.

Also, warp points should have some sort of gravitational attraction or event horizon, so they suck objects closer in. This would make mining WPs harder as you'd have to re-lay the entire minefield when it's been sucked in and destroyed wy the WP. Also, really huge ships passing by through the same sector should get slowed down or even sucked in by the gravitational pull. You're about to use your DCOMCA on an enemy attack fleet when you suddenly locate it in another system...
