Those ships WERE intended from day one TO be lesser than cubes. Not so with the cubes in VOY. When you concoct the "message" where it didn't exist, that falls purely into the realm of fanwank. I'm really getting tired of having to repeat myself because you keep rolling back the discussion as if it never happened and repeating your old arguments. VOY cubes were based on FC cubes which were depicted to be as devastating as QW and BOBW cubes (enough to punch through Starfleet's entire line of defense and assimilate Earth). Saying otherwise is pure fanwank, NOT an intended or implied story element that I just happened to miss because I'm a hater. "Assimilation Cubes" don't exist canonically.
