I see what you mean but the Borg pick and choose what species is worthy of assimilation & who isn't. They also decide what information, once that species is assimilated, is useful & what isn't. If left to a true collective mind, how would there ever be consensus of agreement amoung them of what is worthy and what isn't? Wouldn't it take one dominate mind to make that choice for all? The Borg would still require a mind to organize them, right? We've seen even in "BOBW" that the Borg run on autopilot until certain command words are given. Ex: Assimilate, Regenerate, etc. If they need command words given by the Queen & function on auto-pilot, then doesn't both a dominate & collect mind exist?
