Look at Amadala's reliance on the political process even in the fact of imminent occupation, "I will not condone a course of action that leads to war".
For the sake of nitpicking: it wasn't actually Amadala that said that.
Until recently I would have agreed with you that the N1 probably wasn't a great ship, because I got the impression it was more symbolic than an actual war-machine (though I never bought the argument that it would be outdated technology a mere thirty years later or whatever it is). However, in the comic it's show to be more than a match for TIE Fighters, so obviously it actually is pretty **** good. And that's canon, there's no arguing with it.
Also, who's to say the N-1s in the comics weren't made towards the end of the Clone Wars, or gutted and reconstructed with new systems. A-10s and B-52s are still used decades after their creation and both still excel at their jobs (CAS and heavy bomber respectively).
This is a quote more for the previous poster, but everything was a match for standard Lines. The exceptions of a comic where a pair of Pirate owned Red TIEs captured the Falcon, and a few games like Galaxies or the old Battlefronts. They never received upgrades without Daala or Pallaeon around, and have only gotten worse throughout the years despite the original adequate performance in the movies. Imperial victories and designs are poorly placed to fill a action gap, because of symbolism and the need to justify serious plot armor on important characters. Even the new FO/SF TIEs, are just shooter filler.
As for the A-10, our fighter-bombers don't match it for mission profile and because the chairforce has failed to design a suitable replacement. They don't actually like CAS, it's something that would be better left to ground pilots in the Army and Marines. It's all political bull in the end.
Back on topic,introducing new models is fine. Balancing the meta further can lead to the terminus dropoff while not crippling new ships.
