What happened to all the Magic Find gear in patch 2.0/Reaper of Souls?
The general magic find affix has been removed from the game. So rares and magical items will never boost magic find anymore.
There are still a few legendaries, such as the Nagel Ring, that boosts magic find.
Overall, the effect of magic find has become less useful in RoS as there is a penalty applied to it for legendary tier items for Patch 2.0+.
