I just made some changes to my Corvettes, did an Assassination mission in one as a field-test and, honestly, I didn't even notice that it was supposed to be a wing-mission until I came to hand it in. 
Not completely sure but I get the feeling that the ships in wing-assassination missions get the same magical shield/hull buffs that ships in CZs get.
I guess it's plausible that we're going to encounter high-ranking ships with engineered hulls/shields but I find it a bit irritating that it's always ships in CZs and it's always all of them, regardless of rank, whereas you never encounter one of these super-ships in a RES or at a CNB etc.
I'd rather that all ships were progressively more likely to have big hulls/shields depending on their rank, regardless of where you encounter them.
