The nature of the game almost requires you to level multiple classes, so it's never a waste of time. You're always going to need a second class at 15 to unlock any job. You're gong to want certain cross class skills. For instance, on BRD you're going to want Internal Release from PGL and Blood For Blood from LNC. On WAR you'll want Flash from GLA. On SMN you'll want Swiftcast from THM and Quelling Strikes and Raging Strikes from ARC. These are just brief examples.

It's always a good idea to level up many classes. The skills come in handy.
