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.

...Right...
...In any case, I really don't believe in nerfing vanilla weapons based on what 1 specific modded ship with 1-2 specific modded hullmods can do with them...
I may have written it poorly, that ship I described is what I'm using against Squall spam. It has a large missile slot but I don't actually use it. The experience I shared with the squall not missing was a testing I did with it. I ended up going the meme route: No shields, 2k armor, 10% armor retention once it's stripped, 36.000 hullpoints and very efficient kinetic/emp/high explosive ballistic mounts

It's got targeting AI and 6 Dual Flaks/2 Flaks and is decently able to deal with pretty much any incoming missile that's not, as expected, Sabots (they activate just before the dual AA engages them altough it's not a big deal since I've got Automated Repair Unit) and something like double Atlas Mk II spamming quad squall.
