% of Armour also applies to Elemental damage - NOT WORKING

75%+ resist all on my resistances and I have 90% of armour applies to elemental damage. So in theory I only take 10% of the 25% elemental damage on a hit. I got 1 shot with a fireball from a regular mob in the trial of Schemas, I had over 7k Honor with a little over 100% honor resistance and it by passed everything 0 honor took damage and I was dead even with the Boon where mobs do 30% less damage plus I had the boon of 50% increase defenses. Plus I have noticed on regular maps where the damage of ele hits seems to be bypassing the 90% or that isn't even working.

I always thought it only works against elemental damage caused by a physical hit, but not against spells...
