The game became infinitely better when they closed the Auction House and introduced Loot 2.0. Before you would grind like crazy to basically find pieces of equipment good enough to sell at the Auction House to get gold and then in turn buy the items with the specs you needed for your character. With Loot 2.0, the drops are geared toward your character class which makes grinding much more interesting.
Played alot on the PC version also with the auktion house and liked it because i could sell crap for money. I liked d3 on ps4 until I understand that it was not on a online server, ie cheaters paradise. Since then I play single game or with closed friends, why didnt they make it online on ps4 ? Thats when they destroyed D3 for me. If it have been online i world have been playing it today.
