Recently I was thinking about how to make craftable Sets great/fun/viable/useful again.
To be honest, besides the Sage's Journey Set (and Cains/Borns before the experience got nerfed), the craftable Set bonuses weren't really useful or even fun.
So I was thinking about, how they could look like, updated on the current state of Diablo 3.
On top of that, something I didn't mention in the imgur:
How about a Magic Find rework:
"Magic Find (could also be renamed to something else) now increases the chance for a legendary to roll ancient or primal ancient.
Can now roll as a secondary affix on armor and jewelry slots.
Can roll 3-6% on each item."
