It doesn't really matter if they make certain jobs better/worse than others anymore does it? do people have main jobs nowadays?

Takes a week to level anything to 90, just level everything and pick and choose what you wanna use, if you wanna heal level whm if you wanna nuke sch or blm. If RDM sucks don't use it. These kinds of "job is better than job" things were an issue when it took forever to level and gear a job but not anymore.
