Standard mission NPCs are not engineered.
Only the Wing missions spawn engineered targets.. and those missions do need a reward buff.
Ah okay, I was talking about soloing the wing missions, I thought that was commonplace (and the only missions that used to pay anything half-decent on the boards before). They
definitely need a buff. They're easy for a half-competent pilot in an engineered Corvette/Anaconda/Cutter/FDL but otherwise 5 engineered targets are a bit of a handful for smaller ships or unengineerd ships (at least with my competence levels - the smallest ship I've successfully made a 5/5 kill for the 2x vulture, 2x fdl, 1x Corvette wing is with a Krait MkII engineered to the gills and it took too long to be profitable and consumed all SCBs and 3 SLFs).
I logged on last night and pew-pewed in a HAZREZ for an hour with a wing of 3 and made 58M tagging everything in sight, then did three regular and one wing assassination mission which took another hour by the time I was back at dock with everything handed in. 104M CR in two hours, give or take.
It's a huge improvement on how things were previously, yet still only half what I can easily make whilst almost AFK doing braindead jobs like Robigo or Asteroid mining.
