That's the problem with the world... no one is willing to "commit" to anything
In case you didn't realize this before: "commiting" is out. People want to switch classes and jobs at the press of a button, be it during a battle or dungeon run. They want to be able to paradign-shift from Warrior to Mage to Tank within seconds. They don't want to play a role for longer than needed; they want to be able to adapt to every situation, and they are willing to gladly sacrifice their character's unique character for it. They want to customize. And be able to de-customize at the first sight of problems with their build.

In short, they want the illusion that their decisions really matter, but ultimately want them to be inconsequential.
