tldr; add a helltide chest for target farming aspects from specific classes to make trying new classes a better experience.
A big part of other ARPGs/games of this genre in general is being able to find an item for an alt. Usually you can find leveling uniques/items or build enabling items on your main character that incentivizes you to try another character class
In diablo 4 this simply doesn’t exist. You’re unable to find unique items or aspects for other classes which are usually build enabling/requirements. This essentially means when you make a new character it’s like starting completely fresh. The only thing that’s going to carry over is renown.
When i tried rerolling after about 30 levels i was just firmly in the, “i really don’t feel like starting over” camp and proceeded to just go back to the main class.
It would be nice if there was something i could do to find items for other classes instead of always my own, though i do appreciate when leveling i’m not getting a bunch of sorceress stuff when playing a necromancer. I think that some kind of helltide chest that rewards aspects for a specific class when opening would be a good way to let you work on an alt while playing a main character before the switch. For aspects this would be great, the level requirement would still be a little annoying for uniques but that’s a bigger issue with itemization in general imo.
