Oh finally no more tedious screenshotting of gear, thank god.
Okay someone tell me what's wrong with
my character, I followed you guys' advice and sacrificed some INT so I could get more crit chance, but it's still not good enough even to cope with Act 1 Inferno, what gives?
There's a lot wrong.
1) Get more +All resists. You hardly have any. I'm not sure about EU market, but you can get cheap armor pieces (10k or less) with at least 30-40 +resists, 80-100 Int, and Vit. For Act 1, you should aim for at least 150-200 +resists, and 250-300 for Act 2. Also note, gloves and helm for wizards can reach a max of 300 Int. It's a bit unorthodox that you actually have less Int on your gloves and helm than your other armor pieces. It's normally the other way around.
2) Not sure who advised you to get more crit chance, as resists should've been your #1 priority. In fact, the most popular cookie-cutter wizard build doesn't require any crit chance (Blizz/Venom Hydra). You need crit chance though to make a melee wizard work, and later, it becomes the best way to pump your DPS. But even a melee wiz needs good resists/armor to survive.
3) Dump Ice Armor, it's terrible. Pick up Energy Armor (Force Armor) rune as your armor spell. Drop Frost Nova for Teleport (Fracture). You can keep Diamond Skin, or swap it out for Mirror Images (Diamond Skin is actually only good once you have high resists/armor, which you do not). Drop Wave of Force for Venom Hydra. And lastly, Disintegrate is not a good skill for Inferno until you're better geared as it isn't suitable for kiting. Either go with Blizzard or Arcane Orb, whichever you prefer.
4) As for passives, once you pick up Teleport (and MI, if you so chose), take the Illusionist passive, and drop Prodigy. Astral Presence is better than Prodigy anyway, if you wanted an AP generator, as it also negates the downside to Energy Armor. Galvanizing Ward is a fine choice, as is Temporal Flux, but if you choose a Blizzard spec, swap out Flux for Coldblooded. As you get better geared, you can dump Galvanizing Ward for Glass Cannon.
