It really gave the game alot of replay value. I wish Blizzard wouldn't spoon feed us. But that's the generation now, nobody seems to want to work for anything, its all about now now now.
Blizzard's main audience is going to be the player base it established with the original series and D2 as well as its WoW fanbase. While nothing inherently wrong with that it just means they are targeting an older crowd, generally most of us have families and other activities now. I remember back in my college days playing D2 and coming up with the right build for PvE and PvP and going to town; however it was nothing back then to stay up til 2 in the morning or spend a ton of hours farming or leveling up to 99 and still keep a healthy social life and good grades. Now, if I stay up past 1 I can feel it the next day let alone doing it night after night now. Those days are long past, for me at least as well as most of my friends from college.
I can virtually guarantee you that most of us don't have that time any more. Families, work, and life in general are all going to keep us from playing 8, 6, hell even probably 2 hours a day and Blizzard probably realizes this and is tailoring the game for that population. With all the amount of "game addiction" going through the news the last couple years, Blizzard is also probably doing what they can to possibly curb that before it becomes a major problem, which in turn will allow parents to be more receptive in allowing their kids to play which makes for...well more sales which in turn equals more profits.
The days of UO, EQ, and other S & M games are gone from the mainstream IMO and hardcore mode and full PvP games are going to be relegated to a niche market as sad as it may be for us who grew up on those.
