This is truly a great addition for ppl like me who dislike mf items and do full act runs.( I cant stand doing short repetitive runs)
From the looks of it, the update will come this thursday.

when you max 100 paragon, you dont need a single piece of MF gear. they cap MF to 300%, paragon 100 gives you that, lol.

so people complained inferno was too hard

now inferno is too easy and people complained some more.

being devs is suffering.

Don't farm XP.  Farm gold and items.  Don't worry about pushing Paragon.

Here's a simple exercise.  Take the XP table.  Assume that you run a Perfect Star Ruby in your helm instead of a Perfect Topaz, yielding 31% additional XP instead of 31% MF.  Consider the total amount of XP gained by level 50 Paragon, and look at how many extra levels you would earn with the XP gem in place.

It turns out that the ruby would leave you at level 57 Paragon at that time, about to reach 58.  What this means is that by the time you reach level 50, you would have 21% extra Magic Find, about to be 24%.  But you've been foregoing 31% MF during this entire period of time, leaving you with a huge net loss in items farmed.

When you look at it this way, it becomes pretty obvious that farming XP or trying to accelerate that process is for suckers.
