Int gear offers vastly improved damage output over it's level 55 counterparts, without offering much of an increase in protection. By contrast, dex gear appears to have lost some of it's massive crit. This is different than when the Sewers came out. The mega mage sets then represented a modest increase in damage output, but significantly greater armor.
Unfortunately in PvE, this means that int mages will be holding aggro a lot more ... in gear that doesn't offer more protection that it's 55 counterparts.
