This is more of a useability issue than a bug.

FBX is motionbuilder/kaydara's format for character animation. Motionbuilder fbx characters have control rigs which always face the Z-Axis. Although fbx is useful for other things as well, I think it would be a very good option for MED's fbx import to have a face-the-x-axis option and a scaling percentage option, so that it isn't necessary to constantly rotate and re-scale the character after each import.
