A few items I felt interesting:
"Attack Speed bonus values on weapons and armor have been reduced by 50%"
Heard for quite sometime people should stack attack speed, I guess Blizz thought it was too overpowered.
"Magic Find will no longer be considered when looting objects in the environment such as chests, barrels, vases, pots, and corpses"
Doh!
"The item quality of all components needed to craft the Staff of Herding, as well as the Staff of Herding itself, have been changed from Common to Legendary (i.e. their item names will appear...
The components are now orange... i.e. less likely for you to ignore them :) I've still only found the black mushroom (accidentally very early on in the game, and I almost didn't grab it... because it was white) and purchased the cow bell. One day I'll farm out the rest of the items.
Yeah farming them isn't too bad but does take time. I had a bear if a time farming the recipie in act 4.
I think I got all the stuff with help from panickedthumb for some if it in 6 hours?
