Hi Phasewalker. I wanted to drop in to tell you that these abilities aren't broken. Considering your small sample size, your numbers are actually quite accurate.
As of late I've been reading a lot of post on the forums on how the Devs. just wrecked Merc Bounty Hunters and to all those non believers out there its true. I ran some testing on the Arsenal spec'ed dps using the operation lvl testing dummy on the Imperial fleet here are the numbers as proof
I'll go step by step as to why that's the case, but if you're a TLDR kind of reader: operation training dummies have armor that gives them 35% kinetic and energy DR.
The tooltip says that on average you deal 1804 kinetic damage with Tracer Missile, and you found that on average, your Tracer Missile inflicts 1410 kinetic damage. You include that this is with 5 stacks of Heat Signatures and with High Velocity Gas Cylinder running.
(Tracer Missile) tool tip indicates its dmg is between 1736-1872 kenetic damage i logged 17 stacked armor debuff " which is 20%" average hit normal hit 1410.705. As you can see the damage is way off by the way this is with High Velocity Cylinder on which grants a 35% armor penetration automatically
In this test, you ignore 55% of the target's armor rating. 20% from Heat Sigs + 35% from your Cylinder.
Operations training dummies have 5814 armor rating (not visible to you), which translates through our armor formula to about 35% DR. With your setup, you cut that armor rating down by 55%, effectively turning it into 2616 armor rating. [5814 * 0.45 = 2616] 2616 armor rating translates through our armor formula to 19.5% DR.
Therefore, an average Tracer Missile would deal 1804 kinetic damage, and a target with 19.5% DR would take 1452 kinetic damage. [1804 * 0.805 = 1452] This is only 3% different than the 1410 you reported, which given your small sample size is well within expectations.
The same methodology above applies to your Heatseeker Missiles. The tooltip says they deal an average of 2194 kinetic damage. Since the target has 5 Heat Signatures, that HSM deals 2632 kinetic damage. [2194 * 1.2 = 2632] Cutting through the same 55% armor rating as before, the target still has 19.5% DR, meaning that on average, your HSM inflicts 2119 kinetic damage. [2632 * 0.805 = 2119] This is only 1% different than the 2145 you reported, which given your small sample size is well within expectations.
On too (Heat Seeker Missile) which is also bugged tool tip indicates 2126-2263 kinetic damage and is supposed to receive a 4% damage bonus for each stack of tracer missile which goes up too 5, so you should receive a 20% armor reduction and a 20% damage increase to Heat Seekers Damage. Get ready to be "surprised" fully stacked with high velocity cylinder on normal hits average 2145.25 laughable uh.
All tooltips in the game show damage dealt, not damage inflicted after armor. Our tooltips do not show you the damage the ability will inflict after the target's armor.
with High Velocity Cylinder on which grants a 35% armor penetration automatically which is not calculated in bonus dmg in any way in the tool tip
I hope this clears things up for you guys. To the best of my knowledge, these abilities are still working as intended.
