You should ditch the shield. Go for a offhand. Shield or no shield, you're still gunna die in 1 or 2 hits in Inferno. Find a nice source and up your damage and get some new stats. You should have way more int. Also, you could use more vit.
Second off, your skill build is kinda bad. You lack defensive skills. Ditch the Familiar at least. Try getting Teleport with Wormhole or the one that does a decoy. You can also try Frost Nova, Really good. Which Hydra is that? SHould be only Venom or Arcane, others are that good unless its default with conflag passive.
Get more damage, kite better.
I actually threw this suit together just to tank everything in act 1, since kiting was getting old. I then grabbed as much defense stats as I could to see how well it would work out in act 2. Needless to say I died without a moment to react.
And again the build was just for act 1, my vendom hydra and auto attacks rip through everything there. The familiar was just extra dmg.
Regardless, I haven't been playing the last few days because the game is flat out boring. I've found one "legendary(garbage)" in 90 hours of play and 1 set piece. You basically farm the same act over and over for yellows with a few better stats than what you're wearing.
Hopefully they will bring out some patches to make loot more interesting, otherwise id rather just pop in d2 and play it when im bored.
E: my normal kite suit is 30k+ damage with venom wep/hydra/frost nova and critical mass for the cooldown reduction.
