In regards to the A-wing, i'm sure I read in the rogue squadron series that A-wings could move their guns 180 degrees so they could fire vertically aswell as horizontally.
Also, in the A-Wing's description I call foul saying the A-Wing had a affect on a Star Destroyer. The pilot got hit, slammed into the star destroyer's command bay when their shields were down. Bad call FFG! Love the game though.
Prior to the A-wing crashing in RoTJ 2 A-Wings took out the bridge deflector shield on the Executor, which allowed other A-wing to slam into the bridge otherwise A-wing would have hit the bridge deflector shield and blown up probably taking the shields out but leaving the Bridge intact. So all in all it took 3 A-wings to take down one of most deadly captial ships of it's time, so maybe not a Star destroyer but a super star destroyer yes.
But just before that Ackbar Ordered "All Cruisers, concentrate your fire on that Super Star Destroyer" I think we need to give an entire fleet of MC80's at least the assist.
I agree plus the MC80s' did take a far bit of punishment for their assist
