As someone who plays one class well (Scholar) and another terribly (Warrior), I expect these changes to significantly improve my relative performance on warrior (I don't have the pugilist cross-class skills, and have GLA up to provoke), and scholars I see afraid of cleric stance should also move up from terrible to okay. Ideally there would be more accessible fairy management and DoT monitoring, but even if that doesn't happen, overall we should expect the Gini coefficient of DPS output to decrease on each job, which is valuable and true to their stated intentions.
