Open Job Advancements: Thoughts?

From a personal perspective I've always wanted to try out an F/P, but after the umpteenth link/ring/whatever mule on multiple accounts over the years I have absolutely no desire to level yet another character through level 1-120 if it's not strictly useful in its own right. I also now have the luxury of being able to make a useful level 182 DrK out of my useless ungeared Hero that is currently hogging a valuable character slot on my account.

I welcome this new system.
