Within the novel Blood, Sweat, and Pixels in the book Blood, Sweat Diablo IV Gold, and Pixels, the chapter on the debacle of Diablo 3's launch tells the story of how a Blizzard designer played with the game for literally hundreds of hours, before they found a piece of legendary loot. The orange light finally emerged from an player, the developer walked up to the loot , only to realize the character he was playing couldn't even get it. The loot system was fundamentally broken that even the excitement of grinding for hours before finally having something to take home, was broken.
The issue was later fixed to that you could only get certain loot levels that were suitable for your character, and the rate at which early-game legendary items were dropped higher. Therefore, even if the legendary items you were getting didn't cause any problems however, you would occasionally experience a tiny dose of dopamine to keep you on the hook.
If Diablo 4 gets that right and features a similar loot system like Loot2.0 that was in Diablo 3, then we're already worried about just how much time we'll have to spend playing the game. The Diablo 3 disaster is the most beneficial chance that has ever happened to the series on a continuous basis. If you mix this alongside an Immortal controversy, it feels like Blizzard has a fairly simple plan of how to avoid potholes for it to stay among the best of its customers who are the best of its.
The Diablo 3 community is very vocal about what they don't like, and has been throughout the development of Diablo 3, so we're hopeful that Blizzard will take it into consideration from those fortunate enough to experience large portions of the game before its release. But we'd also bet Blizzard isn't thrilled by the massive leaks of footage that seems to follow after one of these test results.
One of the elements in Diablo 3 that is confirmed to be returning are the limited-time Seasons. They are basically post-game pieces of content, which change the ways legendary items function as well as remixing the content of the base game which adds replayability to a game that's already extremely replayable. Seasons were supported for a significant amount during Diablo 3 buy Diablo 4 Gold, so we're hopeful that they'll become prominent in Diablo 4.
