They could allow us to move the affixes of a charm to a non-legendary item. This would compete with the new item they created as a way to choose between a legendary affix or the affixes of the rune: quality or quantity.
When they talk about the new item to add a legendary power, i thought it would be socketed in the item, and i think that could be an interesting thing to balance it.
Regardless of it being socketed or not socketed, i think that be able to use jewels (you are right, not the charms) as an alternative to the new item, could be an interesting idea to explore. It gives the desicion of a legendary affix or more affixes.
I think they meant the extra affix of their consumable to be in addition to other affixes.
But maybe a new “upgradeable” or “this item can be etched” (with place for rither Simple, Moderate and Complex runes to etch on) can balance the number of affixes.
Jewels for Focus and Effect would have place as well - and everything is balanced to and # of affixes (Especially if you don’t allow etching and jeweling on the same item)
Also, the more we talk, the more I’m convinced Charms are not relevant for this thread.
