Unbreakable Ascendency node + Imbalance Guard

Hi there,
I read about these nodes effect seperatedly so far but I still don't get the full piture of it. So I need some example to fully understand
- For example, I only have body Amour as my Amour source, and it is 1000 Amour. Also, by standard, normally I have 75% element resist
- With Unbreakable, the Amour become 2000
- Now, with iimbalance Guard, it means that I will have 4000 Amour, correct ?
- Okay, now For example I took 1000 Fire damage. Without imbalance Guard, I wiil take 250 fire damage. and with Imbalance Guard, I will take 1000 * (1-0.5) - 0.08 *4000 = 500-320 = 180 fire damage?

In general, can you give me advices that shoudl I invest on Imbalance guard when I play as a Jugg?

In general, if you are building a Jugg correctly, you should NOT take Imbalanced Guard because it limits your damage reduction of any type to 50%.

If Unbreakable puts you at 2000 armour, Imbalanced Guard on top of that will cause you to defend with 4000 armour. You still have 2000 armour for all other purposes, including for Unbreakable's elemental reduction calculation.

If you are dealt 1000 fire damage, 75 res drops it to 250 damage. Unbreakable (not Imbalanced Guard) then applies 2000 X .08 = 160 armour to the 250 damage. 160 armour will do practically nothing to the 250 damage (you need a lot more than this to have some kind of effect).
