lol - sadist.
There's been a mix of npcs so far in the exploration sites I've been to in W-Space.
In terms of numbers - there have been approx 6 exporation sites per system.
Some had a 1/2 BS's to start - then 4 cruisers coming as a second course.
Others started with 4 cruisers - then the dessert was 3 frigs and 4 cruisers. This one dropped some complete subsystems in the drop (can floated next to the wreck).
So far it's been limited to 2 waves of NPC's
