And have been able to do so since at least the Battlespace rule set. Not sure about any older rule sets. So it's not like it is a recent rule change but it does seem to be easily forgotten in these discussions.
The trouble is this paradigm makes me feel like Warships are even more paper tigers/white elephants than they are now. Add in as mentioned it doesn't remove the possibility of orbital bombardment and it just needs a lot more work to me.
you've got to balance needs here. It doesn't eliminate the usage of Orbom, whether by dropships or warships, it just means that it's a tactic that you hold in reserve for missions that really NEED Orbom, or (if you're Smoke Jaguar, Mongolly Malvina, or completely insane) places where you're going to stay that need lots of terrain renovation to get that hi-rad glow.
IOW, what I described is how a WISE commander would use them, there's plenty of room for commanders that are Stupid, wasteful, or insane (or desperate to the point of becoming one of those three.)
essentially it still gives you the space superiority role, and a hell of a threat to brandish, but with reasonable drawbacks that prevent it from becoming THE go-to solution to all problems. a Warship is still damned dangerous, but moves like bringing it in close to a gravity well are marks of significance-the target is too valuable, or too important, or the battle is too desperate, large, or critical to NOT use the biggest gun you have.
and it's a viable gun. just that...if you happen to lose and need to leave, your naval unit's not going to be defending a territory or a point, it's going to be trying to defend itself while making repairs.
Unless, of course, the commander is clinically insane, desperate, or ignorant (hello Lyran Commonwealth Naval) enough to try to jump with a bad controller. (LCS Invincible anyone?) in which case he can try a jump after close bombardment with a de-calibrated drive controller. (Who knows, he might survive?)
The limit also explains why commercial traffic went with a tractor-trailer layout rather than the box vans they started with...and a warship blockade of stable points isn't something to sneeze at in terms of commercial impact to an interstellar civilization, and warships can DO the stable points while having enough thrust to actually make a play at controlling them.
