I got on my Arcane monk
50k Hp 650 All Res , 35K Dps 40,5 Crt chance and 280% Crt dmg and i can farm act 3
few tips on Monk :
1 Stack only 1 resist (+all res on same item)
Dont stand in Molten , Plagued , Desecrator , Fire Chains you will need to kite thoose round a bit.
Your Build in very important this is mine : http://us.battle.net/d3/en/calculator/monk#aiYXgk!ZXU!accbYa <-- This is the Dps Build if u cant survive u might wanna swap Conviction Mantra with Evasion (Hard Target rune)
When using this build u will need a Fast Off hand (btw im Dual Wielding) Fastest would be a Dark Dagger with crt dmg + socket + dex (mine got 680 Dps , 87% Crt DMG , Socket 70% Crt dmg , 80 Dex , 80 Vit.
Its is your off hand who will procc and Produce Cyclones , So a high Crt chance is more important then Crt dmg on items!!! more crits = more cyclones!
Secondly , LoH is nice , but NOT a Must have stat , below 40k Dps its fine but u will still kite thoose packs !
So i went Pure Dps to kill them faster when my serenity is on.
