Got to chime in here... When D3 first came out I was all for it (even with all the draw backs).
Then after about 3-4 months, I lost interest only playing a little every month or so.
Recently, I've gotten back into it and actually enjoy the game more now than I did when I first started. The changes they have made have been for the better for the most part and, although it's not D2, it is starting to fall into it's own.
I've actually found that I enjoy Hardcore characters more than non-hardcore. It adds a completely new element to the game. I have a lvl 19 wizard currently in Hardcore and I'm just taking it nice and slow and enjoying the game. If I want carnage and fast game play, I load up my lvl 60 Barb which I've almost completed inferno solo with. Started finding my first Set items and Legendries... which has been great.
