Lintman's suggestion is very simple (and is similar to some previous ones). But the problem with it, is that it is arbitrary and illogical. If the number of paralyzation turns is set low, it allows totally outclassed fleets to run away from your fleets and go attack your planets, with not much penalty. If you try to fix this problem by making the number of turns being paralyzed quite high, then you've unduly penalized fast, well-supplied fleets, which realistically SHOULD be able to retreat successfully.
OK, now that I've cruelly bashed Lintman's (old) idea, somebody tell me what's wrong with my (new) idea. (Of course, no one will, because it is a great idea!
