No, by no means are great stats a requirement.
However, when you call it a "4 Engine German bomber with decent defensive armament." that implies certain expectations on your part.  It, to American ears at least, makes one think of something like the B-17G.  Generally that has been how requests for the Fw200 have been presented.  If you want the Fw200 for what it was, recognizing that it is inferior to the Ju88A-4, that is well and good.
