Cultural gem requirements?

[htabdoolb]

I'm just starting again after about a year long break. I'm looking to get into cultural smithing, but I'd like to know if the high tier gem requirements for the enchant ore spells are still in effect first. Someone in game was talking about them, and I'd never heard of them before on live. Looking it up made me realize just how insane the original requirements for cultural were.. if I understand it correctly, it would have taken something like 9 blue diamonds to enchant enough mithril bricks to make a high elven cultural breastplate. Is this true for p99, and if so, will it remain so or change at some point? Thanks.
