Squalls are mostly fine. They could just use either better terminal tracking, or as mentioned, a scattering fire pattern.
As they are, even a capital ship can slide laterally and avoid every single shot in a volley if it drops (or angles) its shield.
Gryphon is an oddball.
It's a missile platform, and as such should be as close to the front as possible to ensure its missiles can make contact with thier targets. (This goes double for unguided weapons.)
Except it doesn't have the mobility to evade threats.
It doesn't have the mobility to get into and out of position quickly enough to "hit and run".
And it doesn't have the flux stats or armour to tank damage.
The only way to give it halfway acceptable mobilty is to use SO + UI, which is expensive. And undermines the ship system, which is about increased deployment time.
It's a ship that emphatically
needs to be on the front line to use its weapons effectively, but is entirely incapable of existing there for any length of time.
Even as an artillery platform its not a great option. Gryphon can handle 3x Pilum easily, and flux means nothing in this role. But again it's let down by mobilty, and it's an expensive ship to maintain and deploy.
And most criminal, is that it entirely wastes the potential of it's system, along with most of it's mounts.
Every time I've used a Gryphon, I've been disappointed by it.
Thus:
