I always had the feeling that the Kilrathis caps from WC3 were screaming at me:
"We were designed to be round and scary, but then someone had forced us to try this with 6 straight lines. Don't blame us for this !"
So in my opinion the desgin was killed through the low poly restrictions.
I agree with Nico, that adding a few things at the surface don't make the WC3 kilrathi cap ships look like that much better. The contour will still look like somewhat from a pupils first geometry lesson.
In the manual the WC3 ship design was described as scary though asymetric elements, that seems to make the ships bigger than they are. The Kilrathi cap ships from WC1/WC2 were mostly symetric. I think the asymetric elements should be kept as a development of the Kilrathi ship desgin. So there would be some breach to the older designs. But I also think the ships should become more round.
Since I am not familar with 3D desgin programs I tried to sktech a wildly changed fralthi 2 model to show what i mean.
Since I also can't sketch very well, the model looks weird and the changes are too drastic, but maybe you can catch the direction of the changes I would suggest.
