my fire sorc has meteor/fireball maxed. I would max those prolly for sure...i dunno if others would agree. Also, my sorc wears shako, occy, raven frost, resist ring, maras, serpentskin, and then a rare shield with a butload of resistances...but she isn't made for pvp...she was made for mf. I'm not an expert...but thats would i would do.
