...By the time players reach veteran levels, no one wants to buy regular blue armor/weapons anymore when the set item drops and crafting set armor are far superior and can easily be upgraded. Their value is basically calculated by the chance to get a blue crafting booster from deconstructing them now.
This puts them around 100-150g tops in my mind. You can try to sell for more but it will take forever. And no one wants to sit in zones doing WTS all day, they want to go out to explore and kill stuff.
Blue boosters themselves only sell for 300-350g EA. And you only have a chance at getting a booster when you decon blue armor/weapons. I don't know about you guys, but I have a crap ton of blue boosters, I do not need any more. It's the purple ones I want. Purple gear drops is extremely rare compared to blue drops and this makes it hard to find for deconstruction purposes.
I suggest in a future patch you update the crafting system so that X number of blue boosters can be converted into purple boosters. And, X number of purple can be converted into gold boosters.
This way, blue items will retain their value longer as they would be far more useful than they are now for deconstruction, and it would be very positive for preserving the game economy.
