I would agree with this sentiment. Finding Base Items should be exciting and with work, you KNOW that item will be an upgrade. This is single-handedly why the Tempering system is bad because you are not sure if that item will be any good and only after a ton of investment do you know and even then, it is very hard to tell what is an upgrade vs a side grade.
I would also say that “starter gear” should be way easier to upgrade and deterministic than end-game gear. When you have a GAII item hoping for a GAIII is a lot different than still trying to balance your Elemental Resistances and Armor so you do not keel over and die in a hit and you cannot really build how you want yet.
Having the MW system be the same regardless is kind of stupid. I had a very long post on ways to fix all of this but in short, MW and the Affix Crits should be separate systems. MWing should be straight upgrades.
The MW Crits should be separate and deterministic. This system can work like Honing in LA (which they abandoned for the whole of MW originally). You would pick what you want to upgrade and it has an increasing chance of failure. After a certain amount of failures, it generates a success. This is typically a huge resource sink and grind.
Tempering Scrolls can be repurposed as a Material used to boost your chance of MW success.
