Razortail vs T-Gods

I recently found a

Razortail to replace my T-Gods, which I understood was BiS for my

Lightning Fury javazon. But I'm not noticing any significant improvement in cow clear speed. Is the difference pretty minor or am I doing something wrong?

The reason for using

Razortail is the 33%

Pierce.

This allows you to spend fewer points in

Pierce (possibly as low as 1 point with enough +Skills) yet still have 100% piercing.

Those skill points can then be spent elsewhere.

The only reason T-gods is relevant if you are satisfied with your current

Pierce level %

Razortail + 1 Skill point in

Pierce + 8 or more "plus skill" = 100%

Pierce
L8 = 65% (98% with

Razortail)
L9 = 69% (102% with

Razortail)

Each extra "plus skill" reduce the

Razortail effective bonus.... but is not possible to reach 100% without

Razortail (or Wisdom, but in the end you will want

Griffon's Eye or a "plus skill"

Helm )

Thundergod's Vigor

I think i will try

Thundergod's Vigor with my Javazon too

Doing some thinking, I don't know if the change worth
In my case

Thundergod's Vigor will give me around +10% dmg (and 3 more

Bolts), and my

Pierce with go from 100% to 77%

In a dense area almost always there will be someone behind the main target to trigger a second "explosion".
So considering only 1

Pierce, 1 attack will do 200% (100% + 100%) damage with

Razortail, but will do 194.7% (110% + 110% * 0.77) with

Thundergod's Vigor

An when you consider the chance of a 2nd or 3rd

Pierce the difference is bigger (100% and 100% x ~60% and ~46%)

But if you are already killing almost everything with the first "explosion" ... the extra

Pierce % will not make much difference to you anyway, so that +10% dmg will be better...

100%

Pierce will trigger as many "explosions" as pierced enemies with your

Javelin.
Trust me, this is what you want as javazon in a dense area like cow level.

IMO thundergods is WAY better than the razors. I use it with my java, is awesome.

Quick update. I didn't have enough points into

Pierce. Only had like 78%

Pierce even with

Razortail. After an adjustments, including an Enigma for better positioning, 100%

Pierce and only hitting huge packs of cows, it's not even close.

Razortail destroys

Thundergod's Vigor for density clearing. Still love T-Gods, but it's got a different use on my pally now.
