Best route is actually @ mp 10 I am getting 210 million an hour in public party play
Leoric's manor 1~3 elites x2 shrines --> port to town at gate
Festering woods 4~5 elites x2 shrines --> Port to town after 4th elite kill
Weeping Hollow Full trash mob clear with 5 stacks no side dungeons--> Complete start over*
**Fields of misery is optional, and if you take that option ONLY take decaying crypts side dungeon everything else is a waste of time exp wise.
Each run takes about 11~12 minutes, Don't bother gearing in exp bonus crap, gear for as high of mp play as you can.
I should add I average 200~210 million an hour, however 1 run I did was over 50 million worth, was shrined mostly the whole time.
Best build I've used so far
(I am heavily geared for it though your clearly lacking in meteor gear).http://us.battle.net/d3/en/calculator/wizard#PYXhST!Xeg!bYZaYc
If you encounter a extra health molten elite roll find lure the elite into trash mobs if possible, with my gear each elite pack that isn't molten dies in about 20 seconds.
