funny that you mention this because I was giving advice for D3 to one of the lead developers at Blizzard.

I told him they absolutely had to create bind on equip items and he was like "nah we're not gonna do that".
So, like I said, all the best items were found and the entire system became a hyperinflationary joke.
I was pretty mad he didn't take my advice on a couple of things.

D3 also had one of the worst filters for searching for needed items...
and seemed to personally benefit coders who could tap into the API and sort out the data themselves.
The amount of Blizzard devs exploiting their own system was high.
On top of all the other bad actors.
