Okay ill try to explain this:

EIAS = Effective Increased Attackspeed.
This is the number the game uses to calculate FPA(FramesPerAttack)
EIAS is now capped at 150 for shapers.
EIAS for other skills are usually capped at 75.
EIAS may be called SpeedIncrease in the code. I dno, i heard that word as well..

VINC aka Velocity Increase is basicly the same as EIAS, but for:
Dragon Claw
Double Swing
Double Throw
Frenzy
Theese have different formulas. And i believe its either uncapped or has 200 VINC cap.

IAS = Item based increased attackspeed.
This has diminishin returns, formula to find how many EIAS the IAS delivers are given by the diminishin return formula:
Floor(120*IAS/120+IAS)

SIAS = Skill based increased attackspeed.
This has no diminishing returns.

WSM = WeponSpeedModifier
This has no dimishing return, but is inverted. (low value = Faster)

FramesPerDirection = The baseframes of druids attack, which is different for different weapon classes and even skills:
https://www.mannm.org/d2library/faqtoids/animspeed.html

Actionframe is when the attack is physical dealth.
Actionframe is usually or always given by: (BaseFramesPerDirection+1)/2.

Now EIAS formula, to find ur complete EIAS ammount:
= (Floor(120*Ias/(120+IAS)+SIAS-WSM;1)
As you can see we involve the dimishing return of IAS, we add the SIAS directly 1 for 1, and we subtract the WSM 1 for 1 due to it having inverted function.
The ;1 is to tell excel that it should round the full digit without any decimals.

But since there is a EIAS CAP we include this by using an IF formula.
=IF(Floor(120*Ias/(120+IAS)+SIAS-WSM;1)>150;150;Floor(120*IAS/(120+IAS)+SIAS-WSM;1))
IF formula in excel has this setup:
IF(Logical equation;TrueValue;FalseValue)
So we basicly say:
IF(EIAS is GREATER THAN 150;Then Result is 150;Else Result IS EIAS FORMULA ANSWERE)

Often we know the SIAS and the WSM, and we know the EIAS breakpoint we want to reach due to EIAS table.
And we want to know how much IAS we need to reach the EIAS breakpoint.
Then we use this formula:
Ceiling(120*(EIASbreakpoint-SIAS+WSM)/(120-(EIASbreakpoint-SIAS+WSM);1);1)

The reason why we use EIAS table is due to EIAS beeing the same breakpoint nomather of SIAS, WSM and IAS. And then we use formula above to find needed IAS for breakpoint.
If u used IAS tables there would be so many tables.
Due to SIAS may vary from 0 to 100+ SIAS, and WSM may vary from -60 to +20.

FPA FORMULAS:

The FPA formula for werebear/werewolf and Druid Human for theese attacks:
Normal attack, Maul, feral rage, fireclaw, and i believe at this patch biting attacks as well looks like this:
=Ceiling(FramesPerDirection*256/Floor(256*(100+EIAS)/100;1);1)-1
This is standard formula for most attacks. (there are exceptions like dual wielding attacks, serial attacks, sequence attacks and such, fury is one of theese exceptions)
I believe druid human shape still have 75 EIAS cap though.

The formulas for fury is:
FPD = Frames pr direction.

HIT1 = Ceiling(((FPD+1)/2-0)*256/Floor(256*(100+EIAS)/100;1);1)
StartFrameHit2 = Floor(Floor(0+((HIT1*Floor(((100+EIAS)*256)/100;1))/256);1)*((100-70)/100);1)
HIT2 = Ceiling(((FPD+1)/2-StartFrameHit2)*256/Floor(256*(100+EIAS)/100;1);1)
StartFrameHit2 = Floor(Floor(StartFrameHit2+((HIT2*Floor(((100+EIAS)*256)/100;1))/256);1)*((100-70)/100);1)
HIT3 = Ceiling(((FPD+1)/2-StartFrameHit3)*256/Floor(256*(100+EIAS)/100;1);1)
StartFrameHit4 = Floor(Floor(StartFrameHit3+((HIT3*Floor(((100+EIAS)*256)/100;1))/256);1)*((100-70)/100);1)
HIT4 = Ceiling(((FPD+1)/2-StartFrameHit4)*256/Floor(256*(100+EIAS)/100;1);1)
StartFrameHit5 = Floor(Floor(StartFrameHit4+((HIT4*Floor(((100+EIAS)*256)/100;1))/256);1)*((100-70)/100);1)
HIT5 = Ceiling((FPD-StartFrameHit5)*256/Floor(256*(100+EIAS)/100;1);1)-1

Fury now have 70% rollback, and it used to have 100% before.
According to patch notes blizzard thinks 70% is 40% faster than 100%.

Someone should ping this somewhere. Do you assume that blizzard will nerf it before the update goes live ? sure as hell looks op , i think fury is the fastest melee atack in the game now

Which is exactly what blizzard wanted with the patch make SS top melee build in the game, it is in their original PTR intend notes, if we can’t teleport and have crap mobility we should at least dominate melee

i mean its still a glass canon, you don't have a shield, have no res boost and no defence

you either gear it for good survivability and don't go to cap IAS or go to cap IAS and have fuckall survivability

Yes, it certainly has significant drawbacks, mobility is also a big issue

My example had both those covered. Fcr and teleport is mobility.
You also reach 105frw.
And 2 different shield setup depending on how important the range adder is.

Example:
Grief pb + Stormshield '7fhr/15@' + arach + trangs + 2/20/30'CHAM+15ias/15@' diadem + 10fcr/adds ring + wisp/raven/bk/dwarf + HL + Gores = 68 fcr break, 150EIAS break, light abs, 43% dr, max block, 77% deadly strike.
Swap: Death web 5/-55/2 + 20/-20 jmod.

Fury + rabies.

Cube in invetory:
Cta + demon limb + maras + soj + bk
torch
annie
8 shape skillers
mix of 3max/ar/life and life/5@ scs
Maby something FHR, depending if needed in next patch or not.

If need rangeadder:
Eth Botd GT
= same attack pr sec as grief. (60+20+15 = 95, breakpoint is 83)

Sacrifice 1 ias break if want 99fcr(same for both setups):
HL --> 2/20/adds
Wisp --> 10fcr/adds

Swap to DW side AFTER activating rabies to get max damage.

AR is buffed on both attacks.
Damage is buffed on Rabies.

Im unsure how biting attacks are handeled now.
I assume they took away biting frames and is same as paw/normal attacks now.

If i want +2 range adder berzerker axe + stormshield i go:
Grief ba + 15ias jool + HL = 75.
32 ias is the 5/4/4/4/7 breakpoint(almost as fast as eth tomb in d2lod). And im free to choose between 68 and 99fcr without loosing ias break)

Rabies long duration is a significant drawback, tele shifting is also not ideal, but as you mention it is workable, 105 frw is quite low, because we don’t have a skill FRW which doesn’t suffer drom diminishing returns, that being said Fury Druid is certainly in a much better spot now, if we could get FRW skill it would be all good

They should keep this for werewolf.

However the werebear has been thrown to the Lions.. Its useless now.
They wanted the werebear to be a strong unstoppable force which is slower than werewolf which is supposed to be fast.
And they said that people could use the 3% skill ias pr chargeup in maul to play a fast werebear like before.

However this skill ias in maul is in most cases even with 15 chargeup levels barely able to reach 6 frames with 2 handers, and barely able to reach 7 frames with most 1 handers.

So what they made werebear is a slow strong weak unstoppable "Force" to be reconed.

ya still can't teleport tho in shapeshifting, unless that'll changed that too

and its going to be very hard to stack resistances , esp now since speak amazon with infinity are a thing

He is talking about teleporting in human form then shifting and attacking, it can work reasonably well, specially as a surprise element. i wouldn’t worry about Cs amazon, tomb reaver, fortitude, some extra LR, at 3 frames they will die in 1 fury. I would worry a lot more about FoH in PvP now…
