Hey,
I know there are an awful lot of threads about ordnance being not so great, and how to fix 'em. I just thought about that today again, and came up with the following solution that we might give a try here for a few games:
1) Torpedoes with the target lock header may be fired IN ADDITION to the primary weapon. The torpedo attack has to be the first, the primary attack follows then (no need to give ATC any extra power). Both are separate attacks and may be declared against different targets.
2) Missiles with the target lock header may attack targets outside your firing arc.
Done. Everything else stays the same.
Since all ordnance are one use only that should balance whatever overpower shadow we see here. Yes, Corran could get even stronger for one round, as well as some Y-Wings. But they are also more in danger now, as torpedo carriers can deal quite some damage in a single turn - the X-Wing's a thing then.
