State Of Blue Mage

I leveled blue mage up to 75 within the first two months of its release. I can say that at the time the job was not as powerful as the initial hype suggested. I had access to the job during much of my HNM career and found that the use of it was extremely situational and generally was not desirable. Please, do not mistake what I'm saying. Most linkshells are unable to think outside of the box and therefore it was a job that was not "pro".

My question is thus: What has changed? Obviously blue has gained a lot more job traits and spells but what is the current state of this job? Is this job now valuable, if so why? Can this job out parse other DDs now? Etc. Persuade me why I should or shouldnt take my blu from 75 to 85.
