Well since we know classes/jobs are going to get new skills for the level cap increase of the expansion, let's say what we'd like to see. To make it easier, let's assume the level cap will be 60. To make it realistic, I'm going to assume at least two traits and a stat increase trait for the classes which would mean:

-2 skills per job
-2 skills per class
-2 traits per class
-1 stat trait per class

Now go crazy! I know I'd like to see a fourth ws in dragoon's full thrust combo to compliment their position in groups as a burst damage class. Monks should get two new finishers since they are the combo job. I'd also like to see paladin get some kind of cure. Just some ideas.
