This is definitely a great direction they are taking/going into. hopefully the level will be synced with the rest of the rosters by the time next expansion come. we might not have it as a normal job now, but it's definitely a start. Kinda excited about the new spells though, since that means we're finally getting to stormblood.
what i'm actually scared with this development is by adding new skills, it will actually makes blue mage even more OP than it currently is and that is one thing that we want to avoid. Hopefully it doesn't come to that.
I wonder if Ultimate contents Blue mage only achievement will be added... progging will be a thrill.
