About Hamlet bought crafting components....

[Green_and_a_Half]

I saw from one of the screenshots for ARR that there are Coeurl's being added, which will most likely drop Coeurl skin. That is one of many items that is sold at the hamlet, Aleport specifically. Will the other items purchasable from these hamlet vendors be able to be found in the world instead of just vendor purchased?

NO,
The items sold at hamlet will remain hamlet only,
They might change the name to Hard or superior skin.
The entire reason for the items not being dropped and costing 50-100k (ARR 5-10k) is to make the items crafted from them valuable.
