One solution, imo, is to rework the class quest instances to make you perform your job and use your respective class skills. This would be most beneficial to tanks and healers because those instances currently don't even require you to perform your actual role. NPCs do that for you. The class quest instances are the perfect opportunity to teach players how their class plays, they're just not utilized properly. I think there should be stipulations to completing these instances. Make tanks actually tank, make healers heal, and require each dps class to use certain skills in a certain order. For example, make NIN use 5 Raitons in one instance, and 2 successful TA in a later quest. For drg, each quest requires them keep up heavy thrust and use certain combos a number of times. And you could do that with all the classes. Each class works a certain way, so make the class quest instances force them to play it properly. At the very least, it might take some players from terrible to decent. You can't make a lazy player get better, but you can give the players who care a better introduction to how each class works.
