I'd say they probably need their builds adjusted to better reflect a min-maxed player driven ship. As it stands, they're waaaaay squishier. I was able to solo the mission in my general-purpose viper IV. Didn't mess with the small ships or wait for the cops to arrive- just opened fire on the target and hammered away until they died. Took less than 5 minutes. Would have been even faster if I had swapped my small burst turret (used to healing others in co-op play, and "keeping the pressure" on smaller ships) for a feedback cascade rail; the target was on SCB life support for the majority of the fight.
This was my third try. First try the USS was too close to a planet, and the gravity was causing my ship to overheat just from maneuvering. The second try I was lazy with my pips, and had to run. This try I completed the mission, but accidentally bumped into the target's derelict after I reduced them to 0, and lost over 10% of my hull. The escorts killed me before I could escape, but it didn't matter since the mission was already complete.

There's no way in hell I'd be able to do that vs. a well-built player cutter, engineered and flown to properly abuse its "totally well balanced" advantages. For an example, here's me using the same ship and loadout vs. a CMDR cutter. The only real difference in loadout is that I swapped phasing for oversized on my cytoscrambler, so it's actually 14% more powerful in this video than it was in the first. Note how difficult it is for me to stay close, and how even when I do get shots off with my engineered cytoscrambler (which has more DPS than a huge fixed beam laser- about 50 dps, vs 41), it does nothing. Further note that several other players and NPCs fire on them several times:

Frontier: please bring top-end players and top-end NPCs closer together- preferably ultimately by lowering the RIDICULOUS top end possible for players, and improving the build quality and flight styles of NPCs.
