That won't help much against an 8D pulsar mine.
The way I see it, though, Shadow fighters still aren't all that wonderful. But they've
always been rubbish, they're now just less rubbish. Shadows just aren't good with fighters, and anyone who can't live with that really ought not to be playing Shadows.

Personally, I bought the Shadows boxed set as my first fleet when I started playing ACTA, and quickly realised that the Shadows' only defence against fighters was a pair of Scouts facing each other about 4"-6" apart - any fighter which comes near either Scout is dead. The ability of fighters' shields to work in dogfights and against anti-fighter is not as good as having a +2 dogfight modifier to give you a good chance to actually win a dogfight, or 4" range weapons to let you stand outside anti-fighter range entirely, but it helps. So does the ability of beams to switch to all-round fighter sweeping mode. They don't completely negate the built-in weakness of the Shadow fleet, but they do mean the fleet isn't as helpless against fighters. Bottom line: in answer to the question posed by the subject of this thread, I'd say "yes".
Watch "The Long Twilight Struggle" again. About six or seven G'Quans versus five or six Shadow ships, at least two of them Ancient because they used jump point disruptors. So fighter numbers are more or less even, probably slightly more Shadow fighters. We later see Frazis attacking Shadow ships, we don't see Shadow fighters attacking G'Quans, which implies the Frazis won the dogfight. This tells you all you need to know about Shadows' ability to dogfight. (Unless it's me rolling their dogfights. Frazis can beat
Sentris if I'm rolling for the Sentris, and have done so regularly.
