I would like to see them expand the cross class skills ability so that you can pull from more than just the two classes. Open it up and allow some customization. Reward players who level multiple classes by letting us pull more skills. Because, right now, if you're one of those who only concentrate on one job and only level what you need to cross class for that one job, there's really no incentive to level anything else. Encourage people to play all the classes by rewarding them with the reward of being able to equip other skills.
