I think blizzard overdesigned this game. The real culprit here is certainly the RMAH, they are probably too scared of adding interesting mods that can make people crave way too much for that and create an imbalance on people's desires on the RMAH.
But guess what blizz, the reason why Windforce and that overpowered PoS Enigma were always being sold on Ebay and D2JSP is because those were game-changers, thats why. Few people are going to go to the RMAH to buy stuff just because it has 100 extra dex then the item they are currently wearing, if thats the itemzation you were aiming for, know that this RMAH is bound to fail.
I mean, the mods have stuff like... 1% chance to knockback, 1% chance to freeze... that is as fun as the mods can get.
