To sum up, the Raynor has a HBlue and a BBlue in front, and 2 MBlues, 1 TerSlashBlue and 1Sblue on each broadside.
Well, actually, its BBlue seems to have a terrible field of fire. It can't be fired with the HBlue at the same target at most angles, and it also can't effectively fire at the same target as some of the MBlue's at most angles. Unless there's some unseen bugs/subtle problems with FRED testing I've done, the ship is notable for its HBlue, but compared to a Titan's 3 BBlue's it's rather moot. If you want something good at non-shock-jump engagements and non-forward firepower, it's much more efficient to have some Diomedes and Deimos corvettes.
SBlue's, too? Really? For a top-of-the-line destroyer explicitly designed for line-combat and all-around-firepower roles, why does it have a slow-firing, relatively low-damage beam if it isn't mounted in batteries of at least 3?
Look, balance is significant, I know, but if it's too good against UEF ships, buff UEF ships. Otherwise it's jarring as hell when a state of the art destroyer mounts relatively underwhelming cruiser-grade weapons where you'd expect far, far more firepower to be.
Don't make a huge glass cannon that packs a good but not particularly impressive punch over a wide area--that kind of armament is what you'd want for the ships that can effectively take a beating and slug it out. In ships with poor or unimpressive durability, specialize for asymmetrical warfare and hit-and-run tactics. This is why the Bellerophon is a far more efficient battlecruiser than a Raynor; the Raynor needs greater durability more than anything, otherwise its just plain inefficient or ineffective in its role.
And I'd really rather not play Aristeia and walk away with the impression that the GTVA's next-gen warships are about as impressive as the Mentu. If Sanctus cruisers aren't supposed to get instantly shredded on that mission, don't make Sanctus's super-fragile.
My thought is, good luck opening away the whole Raynor's hull to change a random beam mount with something else that the reactor probably won't be able to sustain on top of the rest.
...huh? It shouldn't be an SBlue in the first place. An SBlue's main improvement over the SGreen is effective range. If you can mount two SGreens on an FS2-era Aeolus, surely you could manage to mount something more than an SBlue on the entire rear half of the 3-kilometer-long state-of-the-art destroyer?
