People who are mad about the "limited job" didn't actually want Blue Mage.

Are you ignoring the fact that Yoshida called the shots for four years now, describing exactly how BLU would be done if it was implemented, and that people kept asking for it anyway?

Four years ago, when people were asking for BLU...
Yoshida: "BLU is interesting. But if we were to do it, it would have to be a solo class with specific content and would be unfit for regular party play."
Players: "Yeah, makes sense."

Today...
Yoshida: "Here, we made BLU. It's a solo class with specific content and is unfit for regular party play."
Players: "OMG WHAT I CANNOT BELIEVE IT HOW CAN THIS BE REEEEEEEEE!!!"

I am not ignoring anything, but if you are willing to provide a source to you're first "quote" from Yoshi-P and the corresponding response I would welcome considering it. I have a difficult time remembering everything Yoshida has said for years ago and the community response is notoriously inconsistent.
