After nearly 1 week into patch 2.1.02, these are my personal experiences.
1. I am currently Harmless, & all Interdictions/random encounters (USS's) have involved nothing higher than an Expert NPC.....with the vast bulk being Mostly Harmless to Novice.
2. In the last 6 days, I've only been interdicted about 2 or 3 times......with all of these interdictions being in low sec or anarchy systems. Cargo or no cargo made no difference at all.
3. Of the 3 interdictions I have faced, only 1 has been successful!
4. The NPC's I have faced have been a decent challenge, but not a massive threat. With that in mind, I think a very, very modest buff to the mid-rank NPC's might be worth considering....though I believe that MoM is planning to make their tactics more varied, which will be nice.
To those who are still saying the AI is "too hard", I won't say "git gud" (unless you specifically want to do combat, in which case its a fair point to make......either that or change ships/targets accordingly), but I will ask people to read all of the very helpful posts, and watch all the helpful videos, on how to best survive an interdiction.....even in the least combat oriented vehicles. Vindicator Jones has done a fantastic video, which I highly recommend you watch!
