As the game is now there is little reason to use any weapon besides gattling guns. Regardless of armor, speed, or design gattling gun's can simply chew them up. i would propose keeping gattling guns as is except for reducing their piercing damage so that heavily armored (or even moderately armored) so that cannons and other weapons can have a chance to shine.
It depends on the scale of the battle. Against the heavy steel armor, gatling guns are really useless because they simply cannot penetrate. Of course, that doesn't mean gatling guns aren't overpowered, but I've seen a highly armored landship shrug off hundreds of bullets like they weren't even there.
I dunno, my experience has been that gatlings are pretty underwhelming sometimes.
Then again, I used to have a policy of putting (at minimum) medium armour (steel or reinforced wood) on anything important, and that level of armour is literally invulnerable to gatling.
To be fair I haven't really made heavy use of gatling guns in any of my designs, mostly (and perhaps unfairly) because of being initially disappointed with their performance against mid to large warships.
I can imagine they may be nice if you have some heavier guns to crack open the target ship's armour, although having to rely on another weapon to function does seem like a cost. Or against swarms of small, light, cheap ships, but again you are paying for it by limiting your effectiveness to certain situations.
i have honest to goodness seen heavy steel get shredded by gattling fir. it may be my eye's mistaking me so i will perform tests and report back
Unless there is a bug, gatling can't even damage regular steel armour, let alone heavy.
Yes Gatling guns LOOK like they are shredding Heavy armor, but actually they just leave black holes and don't hurt the module. I remember sometimes they hurt a crew member though
gatling guns were really effective due to AI rarely using armor.
Well, you can't really use it in conquest unless you find someone with it, and if they do, it'll be hard to get it as ALL THEIR SHIPS HAS THEM, way to exploit your advantages, AI.
