Diablo 4 has seen ups and downs in popularity since it first came out, and there are many ways the game can still be improved upon by Blizzard in future patches, seasons, and even expansions. Issues with Diablo 4's loot and itemization can be solved with players' feedback and Blizzard's intervention, and although it's not ideal that the game's state is not optimal from the get-go, there's a good chance that the most common problems it faces will be addressed soon rather than later. However, there are some things that are unlikely to change even a few years down the line, and Diablo 4's character customization might be one of them.
