Too many replicas are destroying the market
Good thing, Blizzard relay too much on trading, instead of balancing the game.
When you don’t feel surprised when you get anything in the game, the game loses its fun
The problem is when you still trying to farm gold and basic resources on higher difficulties, means the game have serious balance problem.
This because Blizzard doesn’t care of balancing it and even stealth nerf the methods used to have normal quantity of gold/resources on higher difficulties,to make the game slower, counting on dupers(trading) to fix their errors.
