Only thing I recall is during the live letter they said they will be buffing melee classes to compete with BLM. They didnt go into detail on how they would go about doing this.... a STR potency boost seems logically since it would boost melee class without boosting BRD/BLM/SMN. This would make sense because if they boost str potency, they will be buffing all Melee DPS at once so othere classes cant complain of imbalance if they were to re-work class ability potency.
