I've played around with the game a little bit here or there since the disastrous launch. A few new features are nice but largely little has changed. My largest problem (beyond no single-player/no lan) is the absolutely horrid loot design. Gear is boring and in a game that is all about phat loot, that's a death knell. How the hell did Blizzard design this game, make a gear system even more boring than WoWs, and think it would be fine. I don't give a shit if it's 'cool looking'. If the stats are always the same 3-5 things in 'every' item from level 1- 60, I'm not going to give a fuck.
Apparently they are 'looking into' the loot system but at Blizzard speed that means 'we'll fix itemization in the 2015 expansion.'
