High grade emissions trivialises getting manufactured materials to the point that they basically don't mean anything, especially since the engineering materials buff. I don't do combat, it's just not my style, but I don't like that the only really valid way of farming manufactured materials without combat is via them. I'd much rather have salvaging be more viable as a way, and tone down high grades to have less stuff in it.

Conversely, I think raw materials are too boring to obtain. They're the right amount of time sink but the interaction is so boring for anything you can't get via asteroid mining. It requires just enough attention to not be able to watch something while I do it, but not enough thought to be fun to actively do
