Multiple Lawsuits May come to Blizzard in the Coming Future

We come to know that since diablo 3 has been released, Blizzard has been attacked by their own once fans continuously.
A large number of players were not satisfied with diablo 3. They said that this is just a watered down version of diablo 2. But as i see it, I really don't see it in that way. It's the effect of their nostalgia on those games.
I have already spent more than one hundred hours playing diablo so far and I want to say that i have received the full value of the product. However, some players tend to be so dissatisfied that refunds are demanded. As a result, about 7 million copies of diablo 3 sold will be knocked back some. It's unfair to play it and then return it only because you don't like it, which is the similar to that you want you money back at the cinema just because you dislike the movie. It's unreasonable.
To the point, we know that the decision from the Blizzard to monetize the virtual drops tends to be very controversial. Let me explain more. Diablo 3 is a game that is based on equipment drops, such as armor, weapons. There is an auction house in diablo 3 where you are able to make transactions for in-game diablo 3 gold. Cool, right? Then you will need to farm a lot to have good gear and the auction house will reduce the burden. And there is another auction house that you are allowed to buy and sell items for real money. That is called the real auction house.
