Hey guys this is the build I have been using to farm inferno act 3 and act 4.
You don't have to kite mobs with this build, you can almost always just stand in one place and kill everything. You still have to move out of AoE spells like desecrate or plagued of course.

Build description:
abilities
Shock pulse - living lighting
hydra - venom hydra
diamond skin - crystal shel
magic weapon - venom
energy armor - frost armor
frost nova - bone chill
passives
critical mass
glass cannon
paralysis (you can put something else here if you want)
This build offers you almost unlimited survivability with the use of energy armor - force armor and diamond skin. With minimal health diamond skin can absorb around 12 hits and critical mass passive has a chance to lower all cooldowns by 1 sec on crit so you will be able to keep diamond skin up at all times.
How is it possible that you will be getting so many crits?
Living lightning and magic weapon - venom both have incredibly fast rate of attack and they can both crit. With enough crit and attack speed you will be getting so many crits that all your cooldowns are practically non-existent againts multiple targets and less than 2 seconds againts single target.
How you play :
Engage a pack of mobs with your armor magic weapon and diamond skin up. Cast venom hydra and keep it up. Start spamming shock pulse - living lightning, you are spamming this at all times. Now you have no cooldown on diamond skin and frost nova and can use them as needed. You can keep most elite packs perma stunned in frost nova as you can spam it more than once per second. Unless you need to move away from an AoE ability or chase down a mob you just stand in one place and spam your skills.
You can keep most bosses stunned by spamming frost nova and when not stunned your diamond skin tanks their hits quite well. If you need to kite your hydra will still deal significant damage.
Gear needed:
Make sure you have no vitality, some HP regen, stack all damage increase stats such as intelligence, but most importantly attack speed and crit chance. At around 25% crit chance and 2 attacks per seconds you will start getting good results with this build.
Weakneses :
Fast ticking spells - spells like desecrator, plagued or fire chains can kill you really quickly if you keep getting hit by them. Try to keep these elites stunned with frost nova or avoid these types of attacks.
Immune minions, shielded - when mobs are immune to damage you will not be getting crits and thus no cooldown reduction. You will have to either kite a bit until your cooldown on diamond skin finishes, save your diamond skin for when the mobs are shielded or try to stun the mobs in frost nova
Ranged mobs - you will have to chase after them so they will take longer to kill.
Gameplay experience:
I am able to kill around 50% of elites without dying and 40% with dying once or twice but this could mostly be avoided with quick enough reflexes. 10% of elites tend to have a nasty combination of abilities and are hard to impossible to kill. I was also able to beat 2 elite packs at once on a few occasions. Bosses are easily beaten on the first try except for Diablo and first boss in act 3 (Ghom?) which require dodging their DoT abilities. I am also able to quickly switch to my MF gear before the killing blow.
Alternate build
trades hydra for explosive blast , allowing you to spam +75% damage explosive blasts
