Open discussion - Nobody is right or wrong!

So I switched to a Warrior yesterday adn was super excited to see what benefits it would bring. Unfortunately though, a few of the skills from other classes (eg cnj, acn) could not be used as warrior can only use skills from marauder gladiator and pugilist. Sure, the defiance was handy, especaily when combined with Skull Sunder to grant Wrath, but was it worth sacrificing my fail-safes where I bite off more than I can chew? Or being able to heal my chocobo (who is a whole 7 ranks away from learning cure itself)

Looking to hear other's opinions on wether advances jobs were worth it or just a way to show off.
