Let's say I am a 90 mage.

How much more DPS and crit chance will 1000 intellect give me? How do you calculate that sort of thing?

I am also wondering what ranged stats means for a mage. Isn't it only hunters who are using ranged stats? Or is the mage's wand ranged?

How do I know if I should get an item that gives 1000 PvP power or 1000 intellect?

I am also wondering, shouldn't you be hit capped with 5.34% hit, instead of 6%?
