Current: 335 armor, 450 hull, 20 turning accel
My opinion is adding +100 hull (550) and increasing turning accel to 25 m/s2
I am ok with this suggestions, with more turning the Squid could potentially make more reliable use of its aft gun, but I worry that it will give the Squid an even bigger edge against a lot of ships. It is fast enough to reliable dodge a Hwachafish and generally outmanouver four out of seven ships, five if you count vertically dodging the Junker everytime it comes close to losing armor.
The only time I have seen Squids struggle is against Blenderfish or when you consistently load (Lesmok) Gatling and Banshee into their armor before they even engage. Keeping them away from the engagement while hoping your ally can 1v1 the other guy. Turning away for even a second in most ships is not worth it either, because a Squid can easily close on most ships from extreme distances and outmanouver their gun arcs once the ships are finished turning. And if you let a Squid get behind you, you better kill its ally, because once a Squid is behind another ship, which ship can do anything to stop it? A Junker perhaps, but slap an Artemis on that Squid and the easily disabled Junker will stop moving too.
More turning speed also means an easier time keeping front and side guns into arc, then turn around and run off even quicker than now. It can be extremely difficult to fight off a well piloted Squid, because a Gatling and Banshee on a Squid is just as strong as on any other ship. I would want to balance more turning with less forward or less vertical acceleration. Or maybe a minimal decrease in forward acceleration and increasing armor just a little bit so it takes 6 hits to rebuild, making it much more risky when armor gets destroyed.
I lied though, there is one other time I have seen Squids struggle. It is when you throw in two Squids into a 2v2 or it is a disable Squid with another disable ally. But that is because they either lose the ability to quickly kill ships if they don't have a one-clip armor destruction Gatling or have too low armor and hull to effectively stay in the firing arcs of either one of the enemy team's ships which probably feature Gatling and Banshee. But a single Gatling Squid paired with anything not a Squid is, and always was, extremely deadly and difficult to handle when well coordinated and piloted, which should be the definition of competitive Guns of Icarus. So I do not want to see straight buffs for it. Or to make it clear how good the Squid is: Back when the Mobula had its op vertical stats, the Squid was the one ship that could counter it.
