FPE~ Armour Question

Hey,
I was just wondering if anyone had got far enough to see a lot of the armour crafters in Cantha. I would like to know if there are any rare materials that arnt used in Tyria atm but are needed for this new armour.

Thanks,
Jiao

I've only seen one armor crafter and its different armor, but all have the same skin. As for rare materials, if you get enough faction you can trade for amber chunks supposedly used to craft some of the finest armor according to the npc.
