From a meme at the start of the game, the thieve's den became one of the best vendors of the game in TU7, giving access to quality loot with decent rolls as long as you had enough DZ currency. Since TU8, it was removed and now we're stuck with hundreds of unwanted DZ currency and the worst DZ vendors possible. I know the developers don't want us to have god-tier builds too quickly but it's just sad right now. If anybody wants a Named item tied to the DZ, he will have to farm for ages until he either gets one with terrible rolls or just get shanked by another player.
For the sake of the game, we really need this feature back. It even brought funny situations where we have honest players having to go rogue to access it and thus trying to do multiple rogue actions without being mean either.
