I really hope that they pull in the merit point system from FFXI. Maybe not an exact copy, but something similar. A system that allows you to further develop your character after you have hit the level cap beyond just getting new gear would be great. Being able to put extra points into stats or get new abilities would go a long way towards offering some customization.

It would be nice to have 3 or 4 abilities for each class to choose from. I think you could limit it to only being able to get 1 or 2 merit abilities, but make it so that each offers something desired in battle. Maybe make it so two tanks with two different merit abilities is actually preferred over two tanks with the same merit ability, for example. You have to eliminate the "illusion of choice" and offer actual choice.
