Personally I would Blue Mage to be introduced in 4.0 but Blue Mage to have 3 soul stones, A tank, DPS, and Healing so there's a mixture of choices for BLU and abilities since the current set up FFXIV makes it kinda impossible to stick to the BLU lore as far as gathering abilities from mobs since BLU abilities unlock most likely will come from Job Quests, And on a different note, i also would love 4.0 to introduce a new gathering class and crafting class since i really enjoy playing those classes
