Re: First contact borg inconsistency?
It's not until Picard takes over the fleet and orders everyone to concentrate fire on what he knows to be a weak point that the cube starts taking heavy damage.
Seems like Picard would've pointed out that weakness during some tactical briefing during the years between the two Borg invasions?
