Keep the current system but make changes to it. I'd like to see some sort of "catalogue". If you scrap a T1 Infinite Stars, because it got bad stats or ilvl, you can put that effect on one item of your choice. If you scrap a 2nd item with T1 Infinite Stars, you can empower a 2nd item with T1 IS. But keep some restrictions, Jewelery/Weapons/Armor. So you can build up your effects, mix and match it to your desire. Something like a wow-friendly Kanai's Cube.
It's feels bad to do 20% less damage bc you only got avoidance buffs or leech.
