Ah, that's good to know. With Exigency, gearing right is pretty important, because of their special strengths. They're really not terribly strong if you have good anti-missile weapons (like a Guardian + a couple of Hephaesteus on an Onslaught, for example, for anti-torp and anti-spam) and have beams-a-plenty; I tried out a maxed-out Odyssey build the other day, and it blew right through Exigency ships.
A Nautilus is about the worst-possible ship to fight Exigency with; practically all of its weapons are vulnerable to their Repulsor system. Same with trying to nuke Exigency from long range, at least with a mixed fleet; I've lost ships due to missiles getting reversed, hehe.
Overall, I'd say that Glaug definitely are a bit weak right now; one of the things I think is a major problem is that their long, skinny ships are pretty strong, in theory, but take huge numbers of hits to the shields, which have to be huge to deal with their shapes. They tend to get into Flux lockdown too easily, where they cannot fire a lot of their weapons but the AI won't Vent (which I can't really fix until I write custom AIs or write some sort of new type of "shield"). Originally, I wanted them to have small, hard-to-penetrate Shields, but it turned out to be really hard to get the AI to use them well.
The carrier is a big weak spot, as is their lack of any weapons that don't use Flux other than the Shard Gun. That's pretty easily fixed, and making new weapons is always fun. Maybe a long-range low-damage version of the Melter and a small, Flux-less weapon that does something interesting, like do damage and slow ships down? Maybe some new missile that does something wicked, like a big EMP strike, since all of the good missiles are used by the other factions atm?
So, based on what currently ails them, an armor regeneration system that was constantly on in lieu of shields sounds pretty attractive for them; they'd have plenty of Flux freed up, wouldn't take Hard Flux damage, and would not take as many hits from random spam. It'd also give them an edge vs. Plasma weapons, which are the bane of ships with strong shields but low Armor values.
Also, their beam Cruiser with the Megabeam is just not terrifying enough. They have really good fighters, but their Frigates are pretty meh, and their Destroyer with Phase Teleport isn't scary enough, same with the Catcher, which has remained the coolest-looking-ship-that-actually-sucks for a while now, sort of like the Striker.
I wish that spawning new ships in combat wasn't borked and buggy atm; I'd love to give them some way to launch massive bunches of fighters over time from their carriers, too.
