The Blue Mage Argument at a glance

[AC9Breaker]

If you think this will become a regular max-level job in or after 5.0, that is never going to happen. They wouldn't go out of their way to stir all this up and designate BLU as a "Limited Job" just to back out in six months.

BLU is a side quest. Or you can do obsolete content with friends. That's it. That's all it will ever be. There's NO indication of anything else.

I don't understand the point you're trying to make here?
I said Blue Mage is a 5.0 job, so its design choices are strictly for 5.0 in mind. With that said, once 5.0 is here we will eventually see them raise the level cap of the class ergo, more availability in the instances they can take on.

This is information that was released during the announcement. This is not speculation. They have said the level cap will increase. Facts. No where did I claim or say this job would become part of the meta role jobs.
