I want an official answer on this please! MF
I don’t mean to hinder your pursuit for a proper answer but I think the reason you haven’t received an official one is because they don’t want to tell us. So many things in MMO’s have a guide for it, taking out the mystery and exploration of the game. I think magic find is one of those things that we just delve forward with our fingers crossed.
Personally I’ve only ever had good results with magic find with monster loot. I’ve never looted an exotic from a chest aside from the mad king’s puzzle one despite having loads of magic find. Rares are equally impossible for me to get personally as well from chests.
/agree @jukkou
My experience also suggests chests are unaffected, and only loot from monster kills are influenced by MF.

I’ve gotten a rare or two from chests, usually level 78. Never got an exotic from a chest bar Mad King Dungeon.
I max out magic find, I can never get enough of it!
