All of this has been suggested before. The only thing that I want to see them do with the Borg is make them even more mysterious.
Read, the new TNG novels "Resistance" and "Before Dishonor". The Borg finally do what they claimed to all along: ADAPT!
I agree with the majority here. The reason the Borg are so tired and commonplace now is that they explained too friggin' much about them! I mean, we all love the Klingons, because there's still a crapload we don't know, same with the Romulans! Why do they feel the need to EXPLAIN everything?

Why can Paramount never understand that "equation"?
