It's funny, back in the somewhat early days of PP, I pledged somewhere and attempted to do a few things (all playing in open). Got interdicted by a player once, and that worked out pretty well and I enjoyed that encounter. However, I made my life mostly as a trader back then, and while doing non-PP stuff in my power's controlled systems I got constantly interdicted by one of the rival power's NPCs, and it was a Elite level wing with the same npc name on the lead ship. This grew extremely tiresome (getting interdicted every time I went anywhere in my power's systems by the same party), and within about two weeks of this constant attention from Prival's goons, I tossed PP out the window and went on my merry way.
Not sure if that's the kind of AI opposition
@Rubbernuke is looking for, but it was pretty effective on a commander who hadn't put much time in combat by that point. Today, I think this crew was at the level of the wing assassination missions, which are fun for me today but was way over my skill and ship lineup back then.
