So to be honest, I'm quite bored of D3 already. I'm basically done Inferno, I'm massively disappointed in the game to begin with, and its just not fun to play anymore. The only reason I'm still even playing is to make money off the RMAH.
However there is a silver lining, I found this awesome game called Path of Exile. Basically it's what D3 should have been Currently its in closed beta, but its going open beta in august. You can currently get early access though for $10 or really nice members on the forums who get friend invites. I was lucky enough to win a beta key from a group of people streaming the game, so I will also have a chance to get friend invites soon.
