I don't know, I wasn't in on the hype - I just found it and thought it looked cool. I'm enjoying myself ~50 hours in. Apparently it was supposed to be multiplayer? I don't know, but it's def a cool single player game.. especially if you're stoned.
Gold really isn't useful.. Since they removed the auction house gold is kinda 2nd rate. There really is no trading economy since EVERY item is Bind on Pickup, unless they were in your game when it dropped. (as far as I remember)
Side note, I would definitely be interested in started some sort of Zelaron clan/guild/group on there where we can play casually.
no , they pretty much killed off gold and made legendaries drop all the time; made set items the best items for builds, which actually makes it pretty fun to play now.
Torments go up to 13. I haven't messed with any of the Seasons features. Unfortunately, my free time is too limited to remake chars each Season.
