The Diablo community is open about the things from Emily's blog

It was finally fixed to which you could only D2R Items have certain levels of loot that could be used by your specific class, and also the speed at which early-game legendary items were dropped was raised. Therefore, even if the legendary items you got didn't break the game it was still a feeling that you'd occasionally experience a tiny dose of dopamine in order to keep you hooked.

When Diablo 4 gets that right and uses a similar loot system to that of Loot2.0 in Diablo 3, then we're already concerned about how long we'll need to be spending playing. Diablo 3's disaster is arguably the best possible thing to happen to the franchise on a go-forward basis, and combine this and that with the Immortal controversy, it appears like Blizzard has a fairly simple list of potential potholes to avoid for it to stay among the best of its most loyal players.

The Diablo community is open about the things they don't like, and has been throughout the lifecycle of Diablo 3, so we're hoping Blizzard is taking it into consideration from those fortunate enough to cheap D2R Ladder Items have played large portions of the game prior to its release. We'd like to bet Blizzard isn't a fan of the massive leaks of footage which appears to come on the heels of one of these tests.
