Just 2 things.
1.
An Corvette is the Smallest Category of Warships.
Its not an Big Warship.
Big Warships start at the Heavy Cruiser Category.
2.
Actually nope.
An Corvette is not an Capital Ship.
Its not supposed to Fight Bigger Ships.
An Corvette belongs to the Escort Ships and its Duty is to keep Aircraft and Smaller Vessels away from the Capital Ships.
As such Corvettes were usually only Equipped with a Single Heavy Gun Turret on the Front of the Ship.
While the remaining Armament was usually for Fighting Smaller Vessels like Gun Boats and Torpedo Boats as well as Aircraft.
And just so you know.
Corvettes were very Effective at this.
Because they were even smaller and faster than Frigates and Destroyers. They were harder to Hit for Bombers and Torpedo Boats as well as Submarines.
And the Small Calibre Autocannon were much more Dangerous to Aircraft and Boats than the slow Artillery of Destroyers.
But well thats just Speaking Traditionally.
Ingame I think that just like an Fighter can use Anti Fighter Weaponry or use Heavy Weaponry.
An Corvette should also have Viable Weapons for both. Anti Aircraft Escort Duty and Heavy Attack Duty.
I would not Limit it only to Heavy Attack Duty tough.
Especially because in this Game it makes no Sense.
Apparently we wont really get Bigger Ships than Corvettes anyways.
(And honestly unless they really give out some Better Turrets it would be entirely meaningless to give out Bigger Ships anyways....)
So making the Corvette into an Ship only usable against other Corvettes aint going anywhere.
The Joke is.
The Numbers are pretty much Traditional.
Corvettes in Reality had similar Weapon Sizes as Ingame.
An Corvette usually had
1 Big Front Weapon (usually an 100mm or 120mm Turret) Which is Presented by Class 4 Hardpoint. Albeit we dont have Turrets......
1-3 Duty Weapons (usually Anti Submarine Weapons like Hedgehogs or Depth Charges as the main Threat in that time was Submarines. But also Torpedoes in some cases) Which is Presented by the Large Hardpoints
2-6 Secondary Weapons (usually 40mm, 37mm and 20mm Autocannons which were used against Aircraft and Gunboats) Currently Represented by Medium and Small Hardpoints.
In that Regard its actually following things pretty nicely.
The thing is that the Weapons for smaller Crafts are much overdone in this Game.
Gunboats etc which would be the Counterpiece to the Ingame Medium Vessels. Did usually not have so much Weaponry.
Neither had Fighter Bombers which is likely the best Counterpiece for Small Vessels
