Easy answer. There is nothing to play. Look at the past decade. YOu can count the decent online games on a single hand.
Also because this is diablo. People want real change and to make the game better. Instead we have blizzard nerfing every bit of what little fun there is out of the game. More you try the more blizzards little twitless wonders get on the forums and troll your legitimate complaints.
And for complaining at least those people have an excuse to be on the forums. Peopel that say D4 is the best game in all the world are the ones that should not be on the forums if the game is so fun.
Go look at good games. No real white knights because a good game no one feels the need to defend and accept it is not other peoples cup of tea.
