That's not necessarily true. Yes, I take suggestions posted on that thread into consideration, but it doesn't mean that only things posted got brought back. Sometimes an entire set just isn't worth it (I looked through a lot of old items + delish sets). If only like 10% of a set is UB/very expensive in user shops, then and I generally just throw the expensive item(s) from the set into the CS Hustler.

But in the future, it is a good idea to voice your hopes on this thread ! I do check that thread quite often. :)
