Itemization, classes. AH. GAH, And every other "problem" this game has. the awnser is simple.
Blizzard dont hear their comunity.
Either a good fedback or bad feedback is just trowed away to acommplish blizzards goals.
Now look for example at POE forum,
Good and bad feedbacks is taken!
The devs respond and even participate IN game to know opinions from their Users! And Poe is a FTP game. Here in this game (d3) and this forums the people is not listened, not listened for the money they have paid for this game.
Thats all. Just and opinnion.
And sorry for the bad english.
