Everytime I see blizzard interviews or interviewers they always seem to tippy toe around Diablo and the trading aspect of it. Diablo 3 completely destroyed trading when it was released with the Real money AH and then going full circle and removing that aspect all together with BOP and self found play. Diablo 3 also had a Battle.net interface that was barren and felt like can empty community compared to Diablo 2's Battle.net (Characters at the bottem of the screen in a chat lobby).
I really hope we go alot deeper into this Diablo Meta game when questions are asked of Diablo 2 Remastered and Diablo 4.
