CI Freeze Pulser Critical Mass - idea

After ranger passive change and being inspired by kripp last video i came up with this build:

CI Freeze Pulser Critical Mass

There is basicly no need for unwavering stance thanks to Hearth of Oak and Steady Hands. Balistic mastery makes FP easier to use!
Power charges can by used with 2 purposes: dps and safty - spaming cold snap if needed with prolif.

To maintain mana cost of FP there is need for mana leech gem.
6l would look like this: FP - mana leech - life leech - power charge on crit - faster casting - GMP

What do you guys think?

shameless bump

Using Heart of Oak is an interesting idea. With the 50% from ES you have an 80% chance to avoid stun. Try it and post the result. Is it enough to avoid stunlock in fetid pools (rhoas) battlefront (blackguards) and docks (voidbearers)?
Not sure if steady hands is necessary as i don't see how it interacts with the chance to avoid stuns.
Imho Heartseeker (like throatseeker) is not worth the amount of points you have to spend.

From what kripp said (he said he is not 100% sure tho) all the nods that adds chance to avoid stuns are addictive. So basicly with the 80% u said and steady hands this build shoul have 105 % chance to not being stuned.

About steady hands IMO stun is counted as an interruption so it should be additive with rest of anti stun nods.

Gonna have to test this.

@Mark_GGG : does the new 30% stun avoidance node stack additively or multiplicatively with the innate 50% stun avoidance from ES ? because according to the answer, I could just drop armor for evasion eventually.

ES technically does not provide chance to avoid a stun, it provides a chance to ignore one that was caused but not avoided.
Chance to avoid stun prevents that damage being stunning damage. ES kicks in later, when the damage is actually being applied, and has a 50% chance to ignore that the damage was determined to be stunning.
These are not doing the same thing, and apply at different times. They are not, and cannot be, additive with each other.

As i understand it heart of oak is first applied. If it fails and you get stun damage, you will get an ES roll. Steady hands does nothing except giving you a chance to cast while being stunned (still can't move). The total stun avoidance would therefore be: 30% + 70%x0.5 = 65%.

From where u have those 70 x .5 ?

Probability math.

First you have a 30% chance to avoid stun. That means 70% (.7) gets through; of that ES has a 50% chance to save you.

So probability of getting avoiding stun is:

30% + (70% * 50%) = 65%
.3 + (.7 * .5) = .65

With Steady Hands (assuming that Steady Hands comes last) you'd end up with:

.3 + (.7*.5) + (.7*.5*.25) = 73.75%

I was thinking of something similar although I forgot about Steady Hands; I'll have to adjust my build. I was trying to squeeze in dual curse too.

How necessary does everyone think Vaal Pact is for non-hardcore/onslaught play? I was thinking I could get away w/o it.

Heart of oak gives a 30% chance to avoid stun. For the other 70% (where it fails) an ES > 0 gives you a 50% chance to avoid getting stunned by the hit. Total chance to avoid getting stunned after the two rolls is therefore 30 % + 35%.

Edit:
Beat me to it.

Steady hands doesn't give you a chance to avoid stun. You get stunned, can't move but now have a chance to cast spells.
