Invoking rating can augment an argument, but not replace it. You seem to be complaining about three things concerning the Corsair: it has bad AA, its rocket spray is inconsistent, and the turning radius is bad. The first thing is an intentional design decision, it's like complaining that the Janus is bad at sniping or that the Swift Wind can't attack ground. In exchange for being the only bomber that attacks in front of its flight path instead of dropping a bomb below itself, it has the worst AA. The second thing can sometimes lead to lost DPS when attacking a smaller target like an ACU but that's made up for by the fact that the random spread gives it decent utility vs large clumps of armies, more than the Notha. And attacking structures from my experience is totally fine. As for the last thing, I'm not actually opposed to giving them a tighter turning radius, but I think the Janus should have the best turning since it has a swing-wing design that changes its aerodynamics during a turn.
But that's just the Corsair. You were also offering a litany of balance complaints about the Cybran faction as a whole, like the fact that you have to choose between T2 and Gun, or that Cerberus is weak, or the fact that Cybran has no mobile shields, along with slow Mantis turret speed (use zig zag micro). Those are all really silly things to complain about, and in a vacuum I'm not opposed to buffing the Corsair or Making Loyalists Great Again but as a whole, it's very clearly a ranting response to a slew of UEF buffs. Cybran is not underpowered.
