The only way you can kill every single mob in act2 is to have godly gear, otherwise i don't see it possible soloing like act1 inferno. I use this setup
http://eu.battle.net/d3/en/calculator/monk#bcgijQ!YUX!ZaaZcbThe reason i'm using deadly reach+keen eye comes from 3 reasons(rofl): i have 2.26 attack speed making the ability attacking pretty fast( using a blue dagger with 570+ dmg, 1.74 a.s, light dmg+ias 16%, with a shield),the attack itself has the best range allowing you to attack from a small distance thus being able to run faster from deadly attacks, using the keen eye rune because it boosts your def. by half and also allowing me to reach 8k armor.
Even if i kill every elite/rare or whatever mob there is in act1 with 13k dmg and only 23k hp, i even killed 2 elite packs at once, the real problem comes in act2 where i get facerolled in 2-3 secs by a pack of normal mobs....so yes monk really needs godly gear to survive from act2+ inferno.
