I read the title and my first thought was "I hope they say its sold more copies than vanilla".......
I have to say I have owned pretty much every blizzard game(even though I was not a happy blizzard fan with the creation/running of a pay to play game), except WoW(never played Hearthstone). I have lost years to Warcraft 2, Starcraft, Warcraft 3(thank you battleships creator), and insane amounts of time on D2. There wasn't anything left for me to do in D2 when I was quit. SC2 came out and they didn't screw it up by basically upgrading the graphics and a few units...awesome. When D3 came out I was hopeful to start my addiction again, I had been clean for years of D2 but I wanted it back. Then D3 hit, and it was slow, but I made a ton in the auction house, so I kept at it. Made one of every character and got all of them through the game, then with profits from the auction house, I bought 3 of my friends the game and got them to 60 and through it. But the whole time if felt, empty, at some around the end of Sept Borderlands 2 was coming and I played it and never looked back at D3, and never missed.
So if you read that..RoS, my addiction has returned. Those old auction house funds got me to buy the game for those 3 friends who just grumbled "that game again?"(they were not D2 players). Now fast forward a week or two, I have punch in countless hours, one friend has gone from 60 to 70 to 56 paragon levels all on her own, another friend has gone from 60 to 70 to 18 paragon levels, and last guy has gone from 60 to 70 to 12 paragon levels.
They made this game what it should have been all along. I get the anger over vanilla's being horrible, but unless you try RoS, then you are reviewing vanilla and nothing more can be added to the topic. Just my thoughts, I could be wrong...probably am.
