Q u o t e: My point is many people are complaining the RMAH will let players 'pay to win,
it might actually be harder then just "paying to win" then most people think. For instance what if buyouts do not play a huge role in the real money auction house. It would make sense for a seller who is selling a rare end game item to not put a buyout on an item in the hopes a bidding war breaks out. And if a bidding war does break out does the person that finally wins the auction think that he got a easy deal after paying more than he anticipated. At the end of an auction only one person can win the item. The losers of the auction do not receive anything and who knows when another of this item comes back into an auction.
Dupes will not run rampant in diablo 3 like they did in d2. Sure you can pay for items in diablo 3 but its not going to be like diablo 2 in the sense of buying 15 high runes for a dollar. I remember back in lod when harlequin crest was being sold on ebay for 500 dollars shortly after it was released. You could have 500 dollars in your account in diablo 3, see that there is 3 items up that work perfect for your build, and not win the auction on any of them. Then not see those items up again for a couple of days, and then when you do they were crappier versions that are selling for more.
its a player driven economy, players have to find the item, decide if they want to put it up on the real money auction house, then only one player can win that auction. With no dupes, there is no guarantees that paying for gear is as easy as walking into the auction house pressing buyout on the best item in the game for every slot on your paper doll. Blizzard has stated they are not selling gear, so paying for gear will not be like buying the celestial steed in world of warcraft, or buying 5 enigmas in diablo 2.
