It remains incredibly difficult to support mulitple builds on multiple classes.
I actually wish the temper reset mechanic was infinite per item, because this way you only need 1 generic weapon type per class and just swap out the tempers when you go to a new build.
Today however, Let’s say you want a vanilla build for each class. As an illustration, imagine in hoarder’s paradise you have a 3GA variant for each key damage category: Critical Strike Damage, Overpower, Vulnerable. This means a minimum of 6 slots for the weapons and rings x 3 for 18 total slots.
But because temper resets are not infinite, that means you will need duplicates of each base weapon to accommodate for different temper types. One class will easily consume 3-4 stash tabs just to store 3GA items of different damage types and 1 copy of each class unique.
And this is before considering amulets with different passives to support different builds.
Bottom line, the game either needs to go to infinite temper resets or drastically more stash space so a ‘looting’ game can allow players to play different builds and different classes.
