[2019] Best credit maker ship?

Yes you're right.

I'd like to comment. Currently best creditmakers should be T9 premium ships (I personally favored Black even when Missouri was around) and T8's or even T7 can also can be good enough, if you enjoy playing them/on that tier more . As for T10 - those are premiums in some aspects, but credit making isn't their strongest suit (though it can be better then raw researcheable T10 ship, at least due to built-in camo).
