I see what you're saying, but I enjoyed having that defined role. Mainly because it was my choice to take the role anyway.

I think calling it a pigeon hole has too much negative connotation. While it is true, red mages and other classes from xi did very distinct jobs, it never felt that restricting. I don't think many people chose "white mage" and felt as though they had been duped because all they can do is heal. Usually you know what you're getting into, so the predetermined role isn't a problem.
