One of the big issues that I've had at larger scenarios is trying to figure out how much damage a particular ship has taken. With 10 or more people at a table they can get quite confusing to figure out how many times a Tie fighter has been hit. It leads to extra questions that don't really need to happen and drags the game down. Additionally it will tend to slow down the scenario.

That being said my solution to this problem was to make little name tents that show the ship the Pilot skill the attack and defense scores. Along with hull and shield values. I put this into a plastic holder so that you can use a dry erase marker to mark off damage.
