Bug description: Weapon speed is counted to caluclate damage of attacks instead of normalized weapon speed. Normalized weapon speed for ranged attacks is 2.8, when artifact weapon speed it 3.0, which makes hunters make more damage than intendent.
Proof: https://imgur.com/a/zQPUEc0
https://www.wowhead.com/news=281913/battle-for-azeroth-new-formula-for-calculating-ability-damage
In this wowhead article is general formula for attacks which benefit from weapon damage:
(Weapon Damage + (( Attack Power / 3.5) * Normalized Weapon Speed)) * Coefficient * Damage Multiplier (Added brackets for better visibility)

You can clearly see that it uses Normalized Weapon Spped instead of Weapon Speed
Here you can get some basic info what Normalized Weapon Speed is, however its old: https://wowwiki.fandom.com/wiki/Normalization

http://www.thrillofthewild.com/2016/09/stat-conversions-ability-formulas.html (its 7.3.5 but there aren't any changes for NWS)
In link you can see formulas using 2.8 instead of Normalized Weapon Speed cause they provide using artifact weapon (with expection to Auto Shot which takes Weapon Speed which is 3.0)

Lets test Arcane Shot first:
Arcane Shot does 200% of weapon damage. My hunter has 9361 Attack Power and is using 4-9 damage 2.2 speed weapon. Also there is hidden aura to MM hunter which increases damage done by 12%.
Minimal Damage is supposed to be: (((9361/3.5)*2.8)+4)*2*1.12=16784
Maximal Damage is supposed to be: (((9361/3.5)*2.8)+9)*2*1.12=16795
Average Damage should be: (16784 + 16975)/2=16789.5 (Which is also reflected in tooltip)
However when I tested on 100 Arcane Shot sample range was: 13189-13200
When we use Weapon Speed instead of Normalized Weapon Speed math is:
Minimal Damage: (((9361/3.5)*2.2)+4)*2*1.12=13189
Max Damage: (((9361/3.5)*2.2)+4)*2*1.12=13200
This clearly presents that right now Weapon Speed is being calculated instead of Normalized Weapon Speed

Lets also test Aimed Shot:
Aimed Shot does 425% Weapon Damage. My hunter has 9361 AP and is using 4-9 2.2 speed weapon. There is hidden 12% aura. My mastery increases damage done by 20%. Dummy has 27.32% damage reduction from armor.
Min. Damage should be: (((9361/3.5)*2.8)+4)*4.25*1.12*1.2*0.7267=31140
Max. Damage should be: (((9361/3.5)*2.8)+9)*4.25*1.12*1.2*0.7267=31161
Average Damage Should be: (31140+31161)/2=31150.5 If divided by 0.7276 (armor on dummy) its 42812, when tooltip says 42816, pretty close value most likely some rounding here and there.
However when tested on 50 Aimed Shots the range is 24440-24461.
When we use Weapon Speed instead of Normalized Weapon Speed math is:
Min. Damage: (((9361/3.5)*2.2)+4)*4.25*1.12*1.2*0.7267=24441
Max Damage: (((9361/3.5)*2.2)+9)*4.25*1.12*1.2*0.7267=24462
Again Weapon Speed is used instead of Normalized Weapon Speed)


In this example i'm doing LESS damage than intendet because i'm using weapon with LOWER speed than normalized, but hunters with artifact weapon are doing MORE damage cause they have weapon with HIGHER speed than normalized.
Also all number are rounded, however i tried to keep it to as close as possible (naked char, 0 additional mastery/attack power/versatility).
Database shows that Raiders Training Dummy has 2.8k armor (25% reduced damage), but this only applies to equal level players so damage reduction from armor is calulated by value in Thrill Of The Wild post.
Most likely this affect all attacks which uses Weapon Speed/Normalized Weapon Speed.

It is a really nice find, you are completely right. Keep up the work -

Fixed. Normalized ranged weapon attack time is now 2.8 (confirmed by both AskMrRobot and SimC)

What this translates to is that most players (who use artifact weapons) will deal around 7% less damage with abilities that do normalized weapon damage.
In a nutshell (AP / 3.5 * 3.0) is now (AP / 3.5 * 2.8). So the difference is 3.0/2.8 = 1.0714 => Hunters dealt 7.14% more damage than intended with these abilities.
