that ship should be more on the front lines attacking ships smaller than the sj to give the GTVA a great chance of holding the shivans back.
as for the NTF, well spliter groups rise and die. The HOL (Hammer Of Light), the GTI (Galactic Terran Intellegence) and now the NTF (Neo-Terran Front), a shame that is i wanted to see the Repluse kami into the Colossus.
but w/o the colossus? well, the NTF and the shivans would of killed the GTVA quickly no doubt and your talking more and more resources diverted from the Nebula ops to discover and destroy the Shivans, so in the end both Terran and Zod forces will have been whittled down from 60 odd ships to 4 either by destruction or defecting to the NTF.
