In 30-40 hours of watching various pirate streams, I have never, ever seen a Lakon successfully fight back and escape with his entire cargo hold. Just last night I saw a Type 9 with a full combat loadout and shield cells attempt self defense against an Asp, and he failed horribly with a multi-million credit repair bill on top of 20t of lost Palladium.
Sandro's fallacy here is that the trader can improve either outcome by equipping the ship for defense. That is incorrect,
As you say, Type 6, 7, 9 traders almost never escape a competent Asp pirate. Changing the FSD cooldown period won't make a difference in these cases, where the pirate mask-locks the trader.
I saw perhaps the same incident on stream. The "combat" Type 9 only avoided complete destruction because the pirate in the Asp was patient, and even after the Type 9 attacked him, he gave it further chances to drop the 30t demanded. He dropped 20t instead. The damage was a punishment.
I've never seen an NPC pirate say anything like "Cut engines and drop 30t of your Palladium". They just say "Die", "You've made you're last jump", or "I'm going to boil you up".
If NPCs become more capable at combat, traders will start hoping than an interdictor is a human pirate rather than a murderous NPC.
It's been suggested that NPC attacks are more numerous in Solo than in Open to compensate for the last of player interactions. Is that true?
