2.) Being account bound only, if a person quits, they cannot sell the items on the auction house.
3.) Being primary stat + 6 random properties obsoletes all the previous recipes.
4.) These recipes devalue the auction house by allowing players to create similar items that can't be sold.
Fixes: Decrease drop rates for the new recipes significantly and randomize them more, make the items non account bound, make prior recipes have fixed useful attributes + the current random properties. (so that then you might want that 4 random property pair of gloves recipe if it was guaranteed to have atk speed, etc.)
This game is not, nor ever will be an MMO. Stop trying to make it one.
By the way, the whole Nephalem thing and making this a game about a "Chosen One" rather than an "Underdog" story. Yeah, bad idea there also. Stop using that word, I do not think it means what you think it means.
