True, but comparing person A with DRK DRG WAR THF RNG levelled and person B with MNK PLD COR BLM WHM levelled, person B's got a lot more versatility for handling various situations than person A does.
Person A, ultimately, is a damage dealer. They're better at fine-tune tailoring their particular damage dealing job to a situation, but ultimately the situation still has to need *a* damage dealer in the first place. Assuming it does, they're more likely to have the option of being the *ideal* damage dealer for that situation, but if it doesn't, then they're on the sidelines.
Whereas if person B is in a situation that needs a tank, they can be a tank; if they're in a situation that needs a healer, they can be a healer, and so on. They may not be the ideally-suited tank or the ideally-suited healer, but they'd still be much closer to that than if their only options were damage dealers.
Person A may quite understandably hate tanking or healing or support personally, but that doesn't entitle them to whine about there being no tanks or healers or support jobs out there, when they can't bring themselves to be any of those either.
