True, but I'd balance the Interceptor against an A-Wing for game purposes. Make them speed demons. The only thing that can outrun an A-Wing in a straight line is a TIE Interceptor.Let's get nerdy here for a second.
The TIE Interceptor is more of an even fight. The TIE Fighter itself only has maneuverability versus a X-Wing on its side, which is why it had an upper edge on the tight corridors of the Death Star trenches.
Honestly, the A-Wing needs a bit of a boost. Something to call its own. Y-Wings have better armor and Ion Cannons. X-Wings have decent speed and maneuverability, and a solid offensive output. A-Wings are just slightly faster X-Wings with worse guns and missiles.
I am curious what the two new ships will be balanced for. I honestly expected the fourth ship to be a B-Wing and a TIE Advanced.
