Actually, that coulden't be more incorrect.

The combat in the game is completely different approaching it as a Melee DPS, a Ranged DPS, a Tank, or a healer.

Warrior as a Tank is different in feel and execution than Paladin.

Same could be said for Dragoon and Monk, or Black Mage and Summoner ,etc.

Leveling up another class is content, just in the different way you play with it. That's why it's so highly encouraged to play a wide variety: You may find a playstyle you enjoy more, or fond that you enjoy the game more mixing it up.

This is ignoring the class and Job storylines that coincide with them as well. So no, you can't do all content on one class.
