i've been holding on to my random purple weapon drops, but increasingly it seems that they won't be worth anything different in ttk than they are today 1) to infuse a weapon, you need to infuse it with a weapon which is stronger than it, this rules out using any pre-ttk weapons to do the infusing (only ttk weapons will be eligible to infuse) 2) breaking down ttk weapons will give legendary marks, breaking down pre-ttk weapons will give whatever they gave before ttk dropped. it's probably keeping weapons that you like, becuase you never know if they will be ascendible in some future, but for ones that you don't like or use, probably worth just breaking them down now.
