Baseless speculation adds nothing to the discussion. Please take the next day to consider the forum rules before posting again as you seem to be making a habit of this.
More intelligence makes Fireball and Arcane Blast hit harder, but I can also cast more Arcane Blasts in succession with more intelligence thanks to Mage Armor. Maybe static is a bad word to use in that situation, but unless the way Arcane works got changed, it still scales phenomenally well with higher ilvl gear. As long as the options in your Rawr setup are sound, then Rawr is correct and like I said the difference in DPS is smaller than with lower ilvl gear.
