How to better utilize Gats - A Case for Heatsinks

(1/3) > >>

FoxyBillClinton:
I recently posted this to /r/GunsOfIcarusOnline, and I thought it would also be a good idea to post it here.

Way back when I first started GoI, I heard a rumor that Heatsink rounds where better for the gats than greased. I continued to use greased however, because that is what everyone else used. But I never forgot that first rumor. So today, I did the math.

I'll start off with the default values taken from the GoI wiki:
Dmg = 17.5
RoF = 8.33 b/s
Size = 82
Reload Time = 5s

We'll begin with greased:
+60% RoF = 13.33
+20% Size = 98
-20% Dmg = 14

(Size / Rof) * dmg
(98 / 13.33) * 14 = 102.93 Dmg/s

Now for heatsink:
+30% Size = 107
-17% Dmg = 14.53

(107 / 8.33) * 14.53 = 186.64 Dmg/s

So there is a big difference there, but there is the reload time to factor in. And we can factor that in easy. To find how long it takes to empty a clip, we can divide the size by the rate of fire. Then take the highest of the two, divided it by the lowest + reload time, and get a ratio between them.

(107/8.33) = 12.85
(98/13.33) = 7.35 + 5 = 12.35
12.85 / 12.35 = 1.04

So the greased round will become multiplied by 1.04 because it will finish off 4% of the next clip by the time the heatsink finishes its first.

102.93 * 1.04 = 107.05 Dmg / s

The gat with a heatsink round will do 186.64 Dmg / s, and a gat with greased rounds will do 107.05 Dmg / s. Making the heatsink 74.3% more effective than greased.
Also, if we instead take the amount of dmg / s in the same amount of time as the finishing of a greased round clip, it ends up being 106.38 dmg / s for heatsink. So it is still more either way, but by a considerably smaller margin. Only about 3% improvement.

Aside from the increased dmg / s, heatsink rounds also include a  +50% bonus in rotation speed, making it much faster to get on target. And finally, it is also immune to fire as long as the ammo is currently loaded.

TL;DR: Heatsink is 3%-75% more effective than greased at any given time, with the added tactical advantage of faster rotation speed and immunity to fire.

Try this http://ducksoficarus.servegame.com/

It takes 7.35 seconds to shoot greased @ 1039 armor damage
It takes 12.84 seconds for heatsink @ 1177 armor damage

In the extra 5.49 seconds that heatsink is still shooting, the greased gat has already reloaded

DPS per clip (armor)
91.7 heatsink
110.4 regular
141.4 greased

Total DPS
66.6 heatsink
74.1 regular
85 greased

On a side note: buffed greased can 1 clip the armor of any ship, including buffed galleon, while being repaired with mallet

ZnC:
Well, I'll break it down.

(Size / Rof) * dmg
This is wrong.

Dividing Clip Size with Rate of Fire gives you Firing Time. Firing Time is how long the gun stays firing.

Damage per Second = Clip Damage / Firing Time
If you take the total amount of damage in a clip (1372), and divide that with Firing Time (7.4), you get DPS.

Greased DPS = 186

You can work out the rest. :)

ZnC:
Also when considering reload, remember to add it to both.

FoxyBillClinton:
So you are saying if we take the amount of potential damage in a clip, 14dmg * 98 = 1372dmg, and divide by the fire time, 7.35s, to get 186.67dmg/s. Alright, and for heatsink, 14.53dmg * 107 = 1554.71dmg / 12.35s = 125.89dmg/s. So the greased wins by 48%. But there is that long reload time to consider as well. So multiplying by the reload time modifer, as I had described before, brings it to 187.21dmg/s. So greased will have the higher dps by 48.7%, but heatsink would have the higher dmg / clip by 13.5%. So if you were going up against say a gelleon or mobula, a heatsink would allow you to do more direct damage to the hull armor, but against something smaller like a squid or goldfish, it could strip the armor away faster. Interesting :p
