When the game was first demoed in 2011, I was a little confused at the way the then-called initiative worked. The people at the demo table repeatedly stressed that more skilled pilots get to move second and fire first. The thing that bothered me was that your movements are already locked in by time you see the Academy Pilot move his TIE Fighter, so how is that representing an experienced pilot's ability to compensate for the novice's movement? Isn't movement basically happening at the same time?
After watching more videos, reading the cards, and thinking of my own tactics, I finally realize what the benefit is: choosing actions. While it's true that Wedge can't move into a different position it does let him choose whether he'll acquire a target lock or focus depending on if the target will be in his sights, or he will be in the target's sights. Additionally, TIE pilots with higher skill who choose the barrel roll action get to see where the opposing ships have moved before deciding to list to port or starboard, making sure they end up in the best position.
Though this issue hadn't been bothering me for a while, (because I pretty much accepted that the game was the way it was), finally understanding the tactics behind moving last and shooting first makes me even more excited for this game than I already was!
