Currently, the juice simply isn't worth the squeeze. Our unfriendly neighborhood spider-thing simply drops nothing of any value, other than a handful of okay Archgun Mods and the Bloodshed Sigil. Those, however, have very low drop rates, and you can just trade for the Mods and the Sigil looks pretty weird on most frames (IMO.)
My main issue are the Debt Bonds that it drops. These are simply useless, especially since their main purpose is to help you rank up in Solaris United. I see two main solutions to this issue:
1) Make Profit-Taker drop something else instead of Debt Bonds - maybe all of the Toroids: a Vega, Sola, Caldi, AND Crisma Toroid.
2) Make Debt-Bonds actually worth something. Ticker currently sells absolutely nothing in exchange for them. If that character had a much larger, much more appealing inventory of items for sale, Debt Bonds would be good to stock up on.
