Right. Low level Junk and the same junk every time. The drops from attackers should be a bit more randomized. There should be occasional drops of more rare components. Especially if the attacker is higher level.
well what im saying is i do find ALL types not just the same thing... depends on the ships you kill as well.
problem with high grade mats is they are VERY rare and normally require more work then just killing small ships.
Some Mats actually will only drop from trader ships ( type 7-9 w/e ) so if you go in a anarchy system or a Haz site you can probably get away by killing some.
also if ALL mats just drooped from combat it be easy , when it comes to engineers they want you to work for it by doing different things.
what re you looking for exactly?
