regardless how Prime did it, they done it, havent they? Its the result that matters.
Also considering bsm's main border is prime, unless they plan on traveling along the edge of the world they will have to fight prime :l
You might be able to get away with saying that, but since there are other tribes before Prime to compare them to, their result was not nearly as impressive as say, Hulk's results.
And yes, other than Prime they really don't have that much to fight. Besides Guyver I've never been to impressed with the lower part of the world :icon_redface:
