More like Jobs are the only way to be specialised enough for serious group content. You're usually better served going with regular Classes for soloing and simple group content (like FATEs) since you can be more self-sufficient and round out the weaknesses of you current class with abilities from others. For example, taking a variety of damage enhancers as a Gladiator from the other Disciple of War Classes. You'll still be doing less damage than pretty much anyone else might, but it'll be enough that a Gladiator's resilience will get you through.
