New AC cap rules?

[ChaosSlayerZ]

I ok I see now hwo system works.

So warrior get 300 ac, but after that they only 0.45 per raw ac, right ?

But in this case, what is responsible for the thing like: I am putting on 5 AC item, and getting like 12 ac out of it, as level 60 warrior. - something else makes me to get more final AC per 1 raw ac?

also, what is RULE_REAL ( Combat, AAMitigationACFactor, 3.0)?
