I tend to agree with the idea of not showing the battle of Wolf359.
When the Admiral says "The battle does not go well" and the Enterprise arriving at the destroyed fleet worked very well dramatically.
However to please both camps they could always do a little something more with the Mars "Defense" Parimeter than 3 little drones racing to their obvious destruction.
Maybe a shot of squadrons of fighters being deployed from Mars (Futile I know but it would still be cool)
OR (while the Enterprise is enroute to intercept the Borg) we see a young couple walking along the bay in San Francisco when their attention is drawn to a reflection of a flash in the water coming from above, they both look up as we cut thrugh the clouds and atmosphere to the Borg blasting the hell out of Starbase 1.
