I totally like this idea, and been thinking around this could work, but it is not easy...once you start to think how this would fit in the rest of the game play options we have.
Like a FSD field expansion module, that would allow us to use super cruise and do FSD jumps with a ship in tow. and best solution I could think about for the towing part is a towing cable combined witth a towing thrusters, think limpts that are thrusters that can attach to the other ship. the larger the ship, you want to tow, the more towinng thrusters you need to attach. So now we can "move" the towing ship in normal space too and get away with having a towing cable that pull the ship alon,g but once you want to stop, the towing thrusters would do that for us, as the alternative is to physically attach the two ships together. how would that look like?
But sadly many of these cool options does not fit well with the current game design, where we waste lots of resources by blowing ships up left, right and center...
So without any changes to the blowing stuff up all the time, towing would be nothing more than a cool gimmick.
Lets start with conflict zones, if we wanted to incorporate towing in this, then simply disabling (not destroying) enemy ship is enough, you need to disable enemy ships and the ship needs to be towed to your "side", so the goal is to disable enough of the enemy fleet so that they no longer have any reserves left and when that happpens you have won the fight. And i tis not only towing your enemies ships that is useful, towing back your own ships, could put them back into your reserves again after a some "repair" time. So this would mean that we got a few more professions in conlfict zones, we have what we have ttoday, take out enemy ships, but then we have the profession of towing those disable ships, and of course, taking out enemies tow ships is got way to slow them down, so a 3rd profession to escort and defend your tow ships is needed.
War bonds would be based on ships you disable, towed (either by towing yourself or defending a tow to destination). So double pay if you disable and protect the tow.
This is one way we could incorporate towing in conflict zones. to some, this sounds like it would be heaven, and others would think this to be a nightmare....
Pirate hunting, here we can think of find pirate, disable pirate, and either you tow the pirate or request a tow, that you pay for.
Just disabling a pirate gives some bounty, and if the pirate ship is towed and delivered to the authorities, you get a second payout.
Then we now can find abandoned ships to salvage and tow to be scrapped/repaired.
We could have new missions where we can take on towing/salvage missions
And if you find yourself in a ship that is disabled, you can request a tow from either other players or by NPC's
But for everyone that likes to see ships blow up into spectacular explosions would be very disappointed by these sort of changes. It would however be an interesting thing to see how it would affect seal clubbing, as they no longer can blow up other players, only disable them, and do what? sit around for security to arrive? they are not interesting in trying to tow those players to an anarchy system to be sold as "slaves" or whatever..
So what seems like a pretty simple idea quickly spans out to either change many of the mechanism we are used to, or would be mostly a cool gimmick, usable by a few. How many are actually constantly running with both a repair limpets and fuel limpets? I know some players do, but most are not.so for most players, these are just cool gimmicks that can be used... but not really worth it for most of the time. And I fear that just adding towing/salvage to the game would be just the same. And the alternative is quite scary to, changing core fundamental gameplay can turn bad really fast to for many players, but on the other hand, if it actually makes things better, and more engaging/interresting then it coudl be a great uplift to the game... and now I start to think about Fleet Carriers and think about what they could have been, and what we got... so how much cool I think this would be, I fear that what we would get, would be nowhere to close to what it needs to be to be justified change.
