When asked by a fan, Diablo 4 Associate Game Director Joseph Piepiora explains the technical reasons why the stash system hasn't expanded beyond the one additional tab. After releasing a massive update to coincide with Diablo 4's first season, the community had plenty of criticisms and feedback regarding the changes. The pushback on the changes even caused Blizzard to hold a Fireside chat just days later, confirming that it plans to undo many of the changes.
