I had an idea and didnt see anything like this, but i get lost in all the threads easily so if there is one i am sorry.
I was playing with PvP char and got to thinking that an armorer like the system they have would be great. It would do away with rune and dye trader and roll it all in one. making it easier to build your armor and you get a better preview of what you are buying.
Here is my very crappy attempt to make it look how i was thinking.

Am I to assume this is for pve? If it is, it would be difficult to make armor like that all at once. A lot of people barely have enough gold for the armor, let alone to buy runes, dyes, etc. Besides that, why would you want to get rid of those traders? They are also for pc'ing dyes and stuff.

Because runes/insignias and dyes have fluctuating prices they have to be completely seperate. That's why grey dye is at a merchant where prices never change.

my point is to have it all at one merchant. This way you can buy and sell what you want. Without having to run back and forth.
