Not sure what you're actually looking for here with your comment? We admit the item game we created in Diablo III has flaws, we've openly admitted those flaws to our players and that we want to improve them. The next big step is to identify the right way to fix those flaws and, in the process, really re-capture that lust for loot and feeling of "HOLY CRAP ORANGE" that many players feel is missing right now.
It's not just the item game which you created, it's the game in general. At first glance, it looks like I took your quote out of context, but really, a game normally doesn't have the development time of D3 and you could have had at least the "item game" nailed down (as well as everything else) in over a decade.
There is no right or wrong way to fix the item game ... but I am going to guess that the folks that make decisions that maximize RMAH profits will have the final say in how the items will change and how the "RNG" changes.
