The signal to noise ratio on the Diablo forums tends to be pretty terrible (with General being unreadable, the class forums more useful) but this topic really helped me out and I'd recommend it to any Gryffinbore wizards who are having difficulty with Act 2 Inferno or just want to change up their playstyle a bit:
http://us.battle.net/d3/en/forum/topic/5621027826BATTLE MAGE, BITCHES. You still have the option to kite around your hydra and use Ray of Frost for long range stuff, but if you get a nice weapon with cold damage and a high attack speed, I GUARANTEE YOU ALL THE BULLSHIT THAT'S BEEN KILLING YOU
WILL DIE TO YOUR SPECTRAL BLADES. Of course, rather than go the budget route I bought an Azurewrath for about a million that has all sorts of good stats on it, and your wizard has the added benefit of looking like some Final Fantasy reject carrying around a ginormous crazy lookin' sword.
So, not only did I make it out of the sewers, into the Oasis, and retrieve Kuul's head but I even managed to work up a 5 stack doing it! I'm sure I'll be bitching about something else soon when I get stuck, but for now Act 2 Inferno is getting better. There's still certain affixes I have to avoid or drag somewhere else and let them kill me, but champions/elites are going down now too. UNF.
