I don't know what I expected when they announced Diablo III: Reaper of Souls, but man this trailer has me excited. I don't know how long it's going to last so you better watch while you can.
From the video, all the way points are unlocked so go wherever you please. A bounty system is in place where you can go kill a target and grab some good gold. Since the auction house will be gone, there's now enchanting and transmogrification, which should help with getting some good gear.
Seriously, I can't wait to check this baby out. I hope it's not too long of a wait.
