My review is that the jump in the item quality between main program and expansion is simply unduly large. The previous items are worth, so to speak nothing. My witch doctor had with Level 60 really a very useful ceremonial knife (than declarer for Inferno 3 easily enough) and above average HP (just under 100K). After half an hour in the add-on I have a new ceremony knife, added a Legendary, found that the damage by half, the / HP boosts "toughness" by a quarter.
The same game at the Demon Hunter: The Manticore with Marquise Emerald soaked after 45 minutes in a ROS-handed - Crossbow (!).
Speaking Marquise Gems: From level 61 character only drop Marquise Gems. As this gem class was introduced, one needed almost 2,500 of impeccably square stones and 20 million gold to forge a Marquise Gemstone.
To make it clear: ROS is a good game if you start new. But if you have played hundreds of hours to bring his game pieces on a good level, each Blizzard shows the long nose, which can come up with better equipment in ROS after 30 minutes. Although I can not understand the real money stakes: Who has invested money into play on the auction house, I'm just very tired.
