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.
                               

Btw this is consider positive improvement for d3.. i mean it is huge improvement.. cant wait for the patch.. will grind all the way to paragon 100.. for those haters, just quit the game.. end of story.. dun waste ur effort to cry here..

by the time you reach lev 80-90 or above, you should able to kill most mobs in single hit, can upgrade a level within few hours.

total of 10,454,400,000 exp from level 1 to 100
u calculate urself how many mobs u need to hunt lolz

Monsters across the game have had a pass to make their experience and loot rewards more proportional to the effort required to kill them
For example, Imps and Tormented Stingers grant less XP and drop less items, but Lacuni Warriors grant increased XP and drop more items
Experience awarded by level 61-63 monsters has been increased by approximately 60%

This  Turn on bot program, come back after a few weeks, level 100 paragon 

<--- EDIT: edge85, what's that?    Are those wisdom teeth?

Sounds like the attunement system from RIFT

Oh wait, that game failed because of it.

if not mistaken every level up will add 3 main stat, 2 vit and 1 for the rest, 100 level of paragon will get you only +300 main stat, +200 vit (7000 hit points) and + 100 for others, it is not that much by the way.

quoted from anthene ...

need 10 hours of playing for 2 years .. then u can reach level 100 paragon @@

Dont wear any MF gear. I always believed in killing Elite fast rather than using any MF gear. At least, it's more fun.

New Paragon system will make my fast killing more worth while.

Like the Paragon system. 'nuff say...

And if the Paragon system means you'll never get anymore actual Levelling Up? Maybe they would release expansion packs without increasing the level cap...would you like that?

they be adding 2 more chars to compensate, demon and angel

khahahahahhaha

and the expansion is come for free.

no way mang, blizz wants to milk more manis

I uninstalled the game already la  Haven't played since July
