Hello Commander tagos!
I just want to confirm something. You say that it's impossible to escape interdiction - could you clarify. Interdiction is more or less skill-based, with both pilots having a very similar chance. There are differences between ships, but they tend to counter each other out in different ways. If something is occurring that's messing this up, it's likely a bug that can be looked at.
And to carry on with this theme: if you could escape an interdiction you would have, at a minimum, forty seconds of grace period whilst your aggressor is waiting in normal space for their FSD to cool down (not to mention that they will have suffered some damage that you would have avoided). Would that not be enough of an advantage?
From my experience, in the same ship, sometimes NPC interdiction is easy to evade, other times it is practically impossible (ie: simply cannot keep up with the evasion reticle).
