I've tried to politely steer you toward more appropriate posts that don't insult anyone, their time, or their effort. Yet, you continue to post statements that suggest you can do better without any real knowledge of the engine or even how to play the game. Consequently I have reported you to the forum moderators for disrespectful trolling.
You seem like a person who's interested in making the mod better, which is why I consider your attitude such a colossal shame. If you could actually be helpful (such as figuring out how to allow the Federation to "outsmart" the borg) rather than simply criticize, I imagine your input would most likely be very insightful and beneficial. Just something to think about it...
As to undefeatable Borg, just ally with enemy AI factions and then send their fleets against the Borg along with yours. There is also technology that allows for the Federation to "outsmart" the Borg in a very limited fashion: the nanovirus. Learn it. Love it. Live it.
