but anyways, back to guns.
Type 2 is perfect in terms shot\damage\second.
In one shot it delivers 3k hull dmg.
Means it is good for snipershooting...and compensating low quantity of weapon hardpoints.
I almost never used type 3 and small ones...but in one shot they deliver only 1k hull dmg. That means you need keep firing all the time, and when you do backfiring plus avoiding incoming fire...
well I may be quite a nood in all this tactics, but I think that for ships with small amount of hpoints (and those one are the most agile in their class, and cheap) should be equipped with type 2 turrets.
But will be trying both variants - and type 2 and type 3
