But wanting different things does not mean that those different things are always going to be good or free from criticism. And honestly I dont remember a single person on this forum that have wanted a solo Blue mage job. Yoshida might have stated that it would be hard to implement but people just mostly either hoped that they would still find a way without completely taking away the identity of the job or maybe knew that it might never come.
Its just solo content (or a mini game) that probably will be done quite fast and then what? Do fates with it all the time? Clear the blue mage duty (which is a good idea) again and again forever? Other jobs dont need new content spezifically made for them to keep them relevant. Blue mage will need updates and more content for it to keep it interesting otherwise it wont have long to live. And is all that worth is? Couldnt they have balanced it for duty by locking certain abilites for it and still give it the unique duty on top of that? This way we would have had a job that can be used everywhere but also something new to test out with the collection of more spells, and the duty.
