A choice with a wrong answer is not a choice at all.
There are a lot of things in this game where there is a right and wrong way to do them: stats, cross class abilities, etc. But, those are issues of balance, not design. So, they aren't what I want to talk about.
The false choice I want to bring up is job crystals. Why are these, being designed to be essential to high level play, optional? Why have this choice, when one answer is abjectly wrong? All it does is lead to frustration for people when they get matched with a level 55 Lancer.
