A common statement seems to be "You can make your character however you like, but we don't have to party with you", in terms of using unorthodox character design. You'll quickly learn to yield to the wishes of the party, because the only alternative is not progressing, because enemies are too strong to handle alone.
But you're completely free when you're farming/questing/exploring. I play around with all kinds of combinations when i'm not partying. drk/rng sam/drk, etc. Some of them are crazy fun to just play around with. But when I go to party, I'm so glad to have my tried-and-true subjob. Playing around while solo makes you appreciate the strength of certain combinations.
