The promise has been broken.
The Blue Mage we have is not what we were supposed to have.
Half solo - half party.
Designed for Masked Carnival and not well for leveling or soloing contents.
The whole idea of their Blue Mage is conflicting, like 2 identities trying to merge and form a new one.
I think I can say, Blue Mage is my 2nd deception after Lord of Verminion.
