Actually, one of the things I find nice about this game are the ways that they've added synergy between jobs. Bringing two WHMs or two SCHs is almost always inferior to bringing one of each: the SCH's shields mitigate damage, and the WHM's power heals quickly patch up after the attacks that manage to get through those shields.

WAR and PLD have similar synergy - for example, Rage of Halone's STR down effect assists WAR tanks as much as it does PLD tanks.

For DD jobs, BRDs benefit from DRG's Disembowel. SMNs and BLMs (and DDing WHMs and SCHs, for that matter) benefit from BRD's Foe Requiem. It's pretty rare in the game that there's any instance where "throw as many as possible of Job X at it" is the best solution. No 17-BLM Divine Might fight in this game (FFXI reference for one particularly infamous abuse of this type)! I'm not saying that it never, ever happens, but it's pretty rare. The classes are pretty well-balanced.
