Right now we have AGI and INT which allows our spells to scale from primary stats along with our melee - we might need tonnes of INT for 1% spellcrit but it is still there. So maybe they will add some agi>spellcrit talent or mastery? Because as it is the loss of int loses me maybe 11% spellcrit and no melee crit and my melee crit will continue to scale. I'd really hate to roll on gear in Cata and get the "needing AGI over a Hunter? Well half your moves dont even get crit from that!" comments after that.
