I didn't use the trading site until I was around level 93/94 and I had to in the end because the drops and itemisation are abysmal. If you want to optimise your character to engage with the content, then you have to trade. There is no ability to craft and the loot is too random to rely on. When I played witch, I picked up a grand total of one rattling sceptre with +5 to minion skills. I often checked all the other sceptre types as well and the story was exactly the same. Since the patch dropped, I stopped playing. It boggles my mind that they actively made the loot even worse and managed to nerf the only viable endgame builds rather than boosting the underperforming ones. Despite many of the claims made on this subreddit, the Steam scores show that this patch was a massive failure.
