Diablo 4's upcoming loot rework will be so massive Blizzard will let you playtest it early in its first PTR
In a stream today, Blizzard said Diablo 4's next season «goes beyond the scope» of the massive changes it brought to the game in season 2 last year. And for the first time, you'll be able to play with all the new features before the season goes live via a playtest server in a few weeks.
