Good thing though to have multiple crafters, But another point is how are things going to be done storage wise? Are the non-crafters just going to drop all their mats into the guild vault and request stuff? There might already be something in place from the Open-Beta, but I only joined at the end so I did not catch it if there was (Although the vault was very full of Mats which was good heh
)
I am use to playing a game like Eve where Gather's and combat is very separated, but here it is going to mingle together a lot better so the crafters are going to need the stuff they craft too... I don't know just kinda speaking ideas here.
Edit: Is there a list some where of used components, as there is some things that are never used, and can just be sold to random vendor, but if I remember right still show under the components tab. (Chicken claw pops to mind as an example)
