Assuming we're talking DPS against favorable components, the most effective Heavy Gun against a given component often outdamages the most effective light gun against that component (in terms of Damage-per-Second).
Balloon: 173 (Heavy Carronade) vs. 158 (Light Carronade)
Hull: 158 (Heavy Flak) vs 158 (Mortar)
Guns/Engines: 232 (Lumberjack Heavy Mortar) vs 112 (Mercury Field Gun)
Armor: 48 (Heavy Carronade) vs 60 (Gatling)
As you can see from these numbers (which are pretty accurate by my friend's calculations...others can confirm, I hope), against everything but Armor the Medium guns are superior, whether because of raw damage or (in the case of the Flak vs Mortar tie) because of range.
Assuming these numbers are right (I don't contest them), the Medium weapons are even worse than I thought. Because, you see, unless a gunner has an accuracy around 80% (like
everybody on this board, I am sure), most people miss a few shots. Well, a few missed shot on a typical light gun isn't too bad - the rate of fire, large magazine or quicker reload can compensate for that. You can even use the first few shots as tracers.
Largely untrue. Open battlefields and below-average opponents make these weapons easier to use, but skilled opponents or close-quarters fighting just requires a bit more knowledge and ability with those weapons. It doesn't suddenly make them bad.
Largely, but not totally. The lumberjack and heavy flak only arm after some distance (like the Field gun), and if they're mounted on a Spire or Galleon, your adversary chooses the range most of the time.
...A Goldfish is really damn good at blending balloons, boss. A touch of Chute Vent completely negates any advantage the Squid may have in vertical movement to follow the target, and the Heavy Carronade loses basically nothing over the Light Carronade for keeping an opponent pinned or shredding their armor. The greater health and armor allows you to survive more attempts to have someone force you off your target, and also allows you more leeway to actually physically pin your target to the ground. It has different strengths, but it's far from "playing Squid."
Tools are another matter - the Squid pilot can pack a Chute Vent too. I prefer the light carronade to the heavier version, even if it one of the less awkward medium to use; More magazine capacity, more angle, for about the same damage on balloon - it only is less effective against the decks.
Gatlings are terrible at disabling ships compared to a Hwacha: they deal 77 dps to ship components, and their scatter makes it difficult to focus on a single component: it takes over 4 seconds of concentrated fire to take out a single engine. The Hwacha, meanwhile, does 118 dps to ships with a large burst radius. In that 4 seconds you can take out three engines, or all the guns on a Galleon's broadside, or all of a Junker's broadside plus an engine...and so forth. There's no comparing the two for ship disabling.
A Gatling with heavies at short range is a
scalpel; I have successfully disarmed all the guns on all types of ship, many times. It is fast, precise, has a large clip and is especially good at busting guns. Engines? I don't know that much, since when a ship's guns are disabled I switch to charged and finish the hull.
When firing a Whacha, even slowly, you do not "cut" like with the heavy-clipped gat; you "spray", even with the heavies, being about as precise as a katana in surgery. And you better do it right the first time, because the reload... man, the reload... Maybe they're better against engines though, even if that, once again, makes them of any use as long as you can direct your ship to the said engines - which again largely excludes 2 out of the three ships who can mount one.
Additionally, a Heavy Clip Hwacha has incredible precision at ranges greater than a gatling's, and can also damage components near the target area. Finally, the Hwacha deals nearly x5 the Gatling's damage to a ship's hull. The only place the gatling wins is in damage to armor.
And at components, too. And besides, a ship without armor is a ship on its way to a shortened career, as often light guns are paired. The Hwachas don't do that much damage; their edge is, they do that damage pretty much everywhere; If your opponent has even an average engineer, he can undo all damage to the hull 'n' balloon while the gunners fix their guns and - oops, you've got to reload. If the oppo is armed with a gat in range, then you'd better get off the gun and prepare yourself to repair. I have faced many Hwachas with my ol' gats, and most of the time I fire before they do, silencing them. Long range? Bah! An average pilot can see the very visible, dispersed shots coming and somehow negate like half of them, the rest being easily repaired while he's positionning the ship by the time you reload, as two third of the ship that mount these guns are slowpokes.
This I'll grant you. A few more options for Heavy Weapons would be rather nice.
Ah. I knew we would agree on something, sooner or later. ;-)
Thanks for your input, bud.
