Weapon Speed Explained
“Dear BRK, I was looking at your character on the armory and noticed your ranged weapon speed. It’s 1.96. Your weapon is 2.70. I believe the formula for the speed is WEP Speed 2.70 * ( 1 - 20% for Serpent’s Speed) = 2.16. I’m guessing you’re using a ammo pouch to get to 1.96. My question is how is a quiver/ammo pouch factored in? Is it added to Serpent’s Speed making it ( 1- 35%) for a 15% pouch or counted in two steps? Or am I way off base and totally wrong here?
“Also, on my 28th level hunter, my weapon speed is 2.46. The gun is 2.70 with a 10% ammo pouch so it should be 2.43. Why the difference? Of course it could all be to me being totally wrong (see above) and not having any idea what I’m talking about.
“Anyway thanks for your time, patience (an assumption here), and help you may give. Zebediah”
Basically, weapon speed and Haste effects are calculated thusly:
Final_Weapon_Speed = FWS
Base_Weapon_Speed = BWS
FWS = BWS / [ ( 1 + Haste_A ) * ( 1 + Haste_B ) ]
If you have Serpent’s Swiftness, then that’s a 20% Haste increase.
Haste_A = 0.2
If you have a Smuggler’s Ammo Pouch, then that’s a 15% Haste increase.
Haste_B = 0.15
And if you have a Wolfslayer Sniper Rifle, your ranged weapon has an attack speed of 2.7.
Base_Weapon_Speed = 2.7
Let’s do the math!
FWS = BWS / [ ( 1 + Haste_A ) * ( 1 + Haste_B ) ]
FWS = 2.7 / [ ( 1 + 0.2 ) * ( 1 + 0.15 ) ]
FWS = 2.7 / ( 1.2 * 1.15 )
FWS = 2.7 / 1.38
FWS = 1.9565 which rounds to 1.96 and, if you check BRK’s armory profile, you’ll see this matches.
Tada!
“But BRK! What if I get the 10 Haste Rating enchant, what does that do?”
We modify our formula to take the new haste bonus into account, of course!
FWS = BWS / [ ( 1 + Haste_A ) * ( 1 + Haste_B ) * ( 1 + Haste_C ) ]
At level 70, it takes a 10.51 Haste Rating to increase our haste 1%. So we can calculate that a 10 Haste Rating gives us 0.95%. Notice that this is less than 1%, right?
Haste_C = 0.0095
FWS = 2.7 / [ ( 1 + 0.2 ) * ( 1 + 0.15 ) * ( 1 + 0.0095 ) ]
FWS = 2.7 / ( 1.2 * 1.15 * 1.0095 )
FWS = 2.7 / 1.39311
FWS = 1.9381 which will be rounded to a 1.94 attack speed.

I think I may have found the combination of race + talent + weapon to temporarily make you cast faster than pretty much anyone else in the game: Troll + 41pt Beast Master build + Precisely Calibrated Boomstick.
20% boost from 5/5 serpent swiftness brings the AS down to 1.25
15% boost from a quiver brings the AS to 1.086. (round that to 1.09)
15% boost from a 5/5 Imrpoved ASpect of the Hawk brings the AS to 0.9478 (round that to 0.95)
40% boost from Rapid Fire brings AS to 0.6785 (round to 0.68)
And finally, max Berzerk from a Troll will add a 30% boost to AS, bringing the final total to 0.5230
Damn.

So, BRK, have you tried the haste enchant on the gloves in place of agi? I meant to do it, but forgot all about it! I just hate to give up numbers on my AP
But the good people here say that the haste is more dps… and that’s cool too…

I was just wondering If 1.99 attack speed after equiping haste items was the total attack speed ,and do I need more haste gear ,or if it would clip my auto shot If I did get more haste gear? I want to be sure If I get my attack speed to 1.7 its the actual 1.7 on my paper doll not the factored in haste. travisscisse is my hunter will you check me out and give me any sugestions on my build As of now I can bust 1600 dps In 25 man raids when all my procs go off but I want to top 2000. Help plz
