Change game do you think is possible? (Diablo 3)

Recently I came across a forum with questions and suggestions to the administration Blizzard Entertainment... and wanted to offer them to create Diablo more open online gaming world. The battlefield, the type of arati, Versona etc. seasonal tiery. After all, that would be wonderful! Yes, you need to work it would be balance, but as for me, this idea would have brought a huge furor the game.
