jugg fortify help

i'm currently doing doing a sweep jugg, i managed to drop an exalt and i got my self a brass dome which has taken my Armour up to 34k(as i have doubled chest plate armour) and phys damage reduction to 78%.

So with 8 endurance charges this caps me at 90% phys damage reduction. Here's the problem, i'm using fortify in my 6link sweep setup which basically gives my permanent fortify and I was also planning on taking the unyielding ascendancy point when completing Uber lab to give further buffs to my fortify.

Is it worth taking the unyielding point or am i better off taking fortify out of my 6link to use something like added fire?

The estimated physical damage reduction stat shown in the character tab is nonsense. The way armour works is such that the more physical damage a hit deals against it, the less effective your armour is. Your 34k armour might soak up 90% of damage dealt by a white mob by itself, but it will only prevent about 35% of a boss smacking you for 5k. You can always use more DR.

By the way, Fortify works against all damage types, not just physical!
