Hi Alex! Thanks for considering my suggestions, and absolutely, I can share more about it my idea.
So, for transport missions, we have some ships that are not built for that, but that's not the biggest problem, it's the threat level and what ship you are using to avoid being caught by FSD interceptor. This is why some commanders use Fighter Hangar, and contract some NPCs to fly if they are caught, so they can handle or have a breather to try to escape. This is hard if you don't have a good ship.
The amount of cargo is also a problem, as it will increase the number of trips (and the chance to get caught by consequence).
To make this hard, excluding the ships that have access to the Fighter Hangar and some good ships that can handle the high threat, you basically will have this list of ships that will be extremely hard to complete:
Sidewinder, Adder, Hauler, Eagle, Imperial Eagle, Asp Scout, Viper Mk III, Viper Mk IV, Cobra Mk III
Of course, I'm thinking of threat level 6 or more, like the Bounty Hunter reward.
But since this kind of mission could have 3 enemy ships well equipped for each encounter, even a Type 6 or a Type 7 can struggle to complete it, even if you have engineering, because those ships are terrible at maneuvering and survivability.
I mean, this will be really tough, those ships don't have too much cargo and need to make more trips, and if you are caught, it will be a terrible time to avoid being destroyed.
Maybe add those ships too? lol
Cobra Mk IV, Asp Explorer, Diamondback Scout
I hope you get the idea.
If you want more information or even some other ideas, I will be glad to help, but I think I've made it too hard.
I don't know.
