I had this idea and I thought it sounded good but I wanted to see if/what the problems with it might be in actual gameplay...
I'm imagining a new recipe for a special Minimum Level Shard, probably something around L300 (BTA, maybe L400 unbound), so you'd need a fully leveled-up crafter for it. The shard will give an item a ML of 1, but when you equip it (or whenever your character refreshes, if you're already wearing it), it becomes ML of your level and scaling affixes would rescale accordingly. This way the item will grow with you as you level up.
Third slots might remain inactive until L10, or it might make those items absolute ML10. Likewise, augments would probably enforce an absolute ML as well.
I think the advantages here are obvious for those cycling through Heroic and Epic TR chains, though of course named items still can offer better bonuses once you reach the appropriate level. I think anything that helps rein in bank bloat is something everyone will enjoy![]()
