Why don't people stick with the healer they started with?

[Kuroyasha]

I don't know if I will or will not switch. I'm highly leaning towards Scholar right now. I like to heal in general. I enjoy it on both classes. I just have so much invested into Whitemage that it is going to take a little for me to catch up.

Here is my reason for switching. People can play one way. To play their favorite job. Or people can play another to be the best at what they do. I'm playing a role as healer. Not a whitemage in particular. I want to be the best healer I can be.

How come you're not a keeper of the moon then? xD
