Should I be decontstructing all these named set items or should I be putting them in my bank. I have a whole lot of named stuff and a smaller amount of generic Armor. I want to build up my crafting level.
If it drops, you can farm it again (and will probably get better the next time). Deconstruct away!
Anything below CP160, you grow out of very fast, and it's not worth keeping. By all means use it for a while, before breaking it down, and then it won't feel like a waste.
