I think Novas
Should be (one of) the equalizer for the little guy. Perhaps a cost scale that rises with the player score. I tried the hit and run for twenty minutes in Beta and gave up after killing only 1 million defensive fighters. I could wait til the end of the game to take that sector. I want to play for 10 -15 minutes at a time and enjoy the game- not get tired of it.
I'd also like to see mine disrupters for all those minefields
